Key Highlights

• The "Murph" — a one-mile run, 100 pull-ups, 200 push-ups, 300 air squats, followed by another one-mile run — was created by Navy SEAL Lt. Michael P. Murphy and his friend Kaj Larsen during BUD/s training; it is now performed worldwide as a Memorial Day tribute.
• Annual gatherings, including the Lt. Michael P. Murphy Museum event on Long Island, draw hundreds of participants who complete the workout together to honor Murphy and other fallen service members.
• Completing Murph safely requires specific preparation, sensible scaling, and attention to technique; structured training plans and community events make the challenge accessible to a broad range of athletes.

Introduction

A single workout has become a ritual: every Memorial Day weekend, thousands lace up their shoes, chalk their hands, and take on a demanding sequence of running and calisthenics designed by a fallen U.S. Navy SEAL. More than physical exertion, the Murph Challenge functions as a public act of remembrance. Its appeal rests on several converging forces — an intensely demanding structure, the story of the man behind it, and a fitness community that has adopted endurance and camaraderie as a way to honor sacrifice.

This article traces the workout’s origins, explains why it resonates so widely, and provides practical guidance for anyone who plans to participate. The Murph is equal parts tribute and test: it asks athletes to confront fatigue, manage pacing, and push past self-imposed limits while remembering why they are doing it. The result is a ritual that transforms ordinary gyms, parks, and town squares into collective spaces of memory.

The origin story: Lt. Michael P. Murphy, BUD/s, and a workout born of brotherhood

Lt. Michael P. Murphy’s name is inseparable from the workout that now bears it. Murphy conceived the sequence during basic underwater demolition/SEAL training (BUD/s), a course characterized by gruelling physical and mental trials intended to forge teamwork and resilience. The routine he developed alongside friend and fellow trainee Kaj Larsen was simple in design and brutal in application: a mile run, a high-volume sequence of pull-ups, push-ups, and air squats, then another mile to finish.

Murphy did not design the workout for public performance. It came from the practical goal of building functional strength and endurance that would matter in operations where stamina, upper-body pulling strength, core resilience and leg conditioning are all essential. The regimen also encoded a culture of shared hardship — a way for small teams to test themselves together and push one another forward. That shared aspect explains why the workout travels easily from special-operations training yards to CrossFit boxes, community fitness parks, and amateur running clubs.

Murphy’s story took a tragic turn in 2005 during Operation Red Wings. He was killed by Taliban fighters after exposing himself to enemy fire in order to call in reinforcements to try to save the remainder of his squad. The circumstance of his death — an act of deliberate exposure meant to save others — shaped the moral gravity around his name. His heroism received national attention, and the tale of Red Wings later reached a mass audience through the 2013 film Lone Survivor, which dramatized the operation.

Those two strands — a demanding workout and a compelling story of valor — merged into a cultural practice. Over time the Murph migrated from training tool to ritualized test, and Murphy’s name became a shorthand for both physical challenge and memorial.

Anatomy of the Murph: What the workout is, why it’s demanding, and common variations

At its core the Murph is straightforward:

• 1 mile run
• 100 pull-ups
• 200 push-ups
• 300 air squats
• 1 mile run

The order places the high-repetition upper-body work in the middle of the workout, bookended by two runs. The overall stimulus tests aerobic capacity (the runs), muscular endurance (push-ups and squats), and upper-body pulling strength (pull-ups), in addition to mental toughness and pacing judgment. That combination is what makes the Murph more than the sum of its parts.

Common ways people approach the workout:

• Rx (as prescribed): Complete the entire sequence unpartitioned or with minimal breaks, often wearing a weighted vest or body armor to honor the military origins. The vest tradition adds an additional load and increases cardiovascular and muscular demand.
• Partitioned sets: Split the pull-ups, push-ups and air squats into manageable rounds — for example, 20 rounds of 5 pull-ups, 10 push-ups, 15 squats; or 10 rounds of 10-20-30. Partitioning is the most common strategy because it preserves form and reduces the risk of collapsing mid-workout.
• Scaled: Reduce total repetitions, substitute ring rows for pull-ups, push-ups to knees, or perform goblet squats instead of air squats for those with mobility or joint limitations.
• Team format: The reps are distributed across a group so that the set is completed collectively, offering a social and logistical alternative to individual completion.

Why the workout feels so much harder than the math implies

Three design features make Murph disproportionately difficult:

1. Cumulative fatigue: Running in the heat, then immediately performing 600 calisthenic reps, saps the central nervous system and challenges movement economy.
2. High-volume upper-body pulling: Pull-ups are comparatively taxing when done in large numbers, especially after running and push-ups have already recruited core and stabilizer muscles.
3. Mental load: The workout demands sustained focus for a long period. Fatigue magnifies small technique flaws that can compromise efficiency or cause injury.

Because of these factors, completing Murph while preserving form — and the intention behind doing it — requires planning.

How Murph became a Memorial Day tradition: rituals, community events, and the Long Island example

The Murph evolved into a Memorial Day ritual largely through grassroots adoption. CrossFit communities, veteran groups, and locally organized fitness events adopted the workout as a way to combine public exertion with commemoration. Its simplicity — minimal equipment, easily scalable, and publicly performable — made it ideal for outdoor gatherings and box-wide events.

On Long Island, the tradition has taken a particularly visible shape. Chris Wyllie, a former SEAL who operates the Lt. Michael P. Murphy Museum, hosts an annual Murph event that draws participants of varying fitness and military backgrounds. Wyllie reported growing participation; an event that had 280 sign-ups last year was expecting 366 the following Memorial Day weekend. He described the experience as humbling for many who attempt it and emotionally meaningful because it brings people together to honor the fallen.

Kaj Larsen, who helped devise the workout with Murphy, captured the sentiment succinctly: “I think Murph is somewhere up there in Frogman heaven, smiling down at all these people who honor fallen service members through sweat and sacrifice.” That phrase — sweat and sacrifice — encapsulates why the workout resonates as memorial. The exertion is a deliberate, embodied form of remembrance: participants literally sweat in honor of those they remember.

The community events typically incorporate several elements:

• A moment of silence or a short ceremony honoring those who have died in service.
• A collective start time, often at sunrise or early morning, aligning the physical effort with a solemn commemoration.
• A variety of participation modes: individual Rx, scaled, relay or team formats allow a range of fitness levels to join in.
• Fundraising or awareness activities linked to veteran charities, museums, or family support groups.

These events transform the workout from a solitary physical test into a public act of memory.

Preparing for Murph: Practical programming, technique, and pacing strategies

Preparing for Murph requires attention to three domains: cardiovascular conditioning, muscular endurance (especially pull-ups), and pacing/strategy. Training should begin weeks or months in advance depending on the athlete’s baseline fitness. The following guidance covers a progressive approach for athletes with a basic level of fitness who aim to complete Murph safely.

Principles to follow

• Train specificity: Practice the movements (pull-ups, push-ups, air squats) under fatigue. Simulate the demands of the workout by combining running with high-rep bodyweight work.
• Progress gradually: Increase volume and intensity in no more than one factor (volume, intensity, or frequency) per week to reduce the risk of overuse injury.
• Prioritize technique: Maintain scapular control in pull-ups, a stable plank position for push-ups, and hip-hinge awareness for squats to preserve efficiency during high-rep sets.
• Manage pacing: Start conservatively on the first mile; the second mile is often the limiting factor if athletes expend too much energy early.

A sample 12-week progressive plan (three workouts per week, with optional supplemental work) Weeks 1–4: Base and technique

• Workout A: Interval running — 5 x 400m with 90s rest. Pull-up practice: 5 sets of 5 strict pull-ups (use band assistance if needed). Push-ups: 5 sets of 15. Squats: 3 sets of 25.
• Workout B: Long run 5–6 miles at conversational pace. Accessory: core work (planks, hollow holds).
• Workout C: Conditioning — 3 rounds for time of 800m run, 10 pull-ups, 20 push-ups, 30 air squats. Rest 3–5 minutes between rounds.

Weeks 5–8: Volume building and practice under fatigue

• Workout A: Interval running — 6 x 400m with 60s rest. Pull-up progression: 5 sets of 6–8 (weighted negative reps if necessary).
• Workout B: Tempo run 3–4 miles at moderately hard pace. Mixed sets: 6 rounds of 100m sprint + 10 push-ups.
• Workout C: Murph simulation (scaled): 0.5-mile run, 50 pull-ups (partitioned), 100 push-ups, 150 squats, 0.5-mile run. Focus on pacing and recovery between sets.

Weeks 9–11: Intensity and taper

• Workout A: Race-pace run: 1 mile repeats at slightly faster than planned Murph mile pace, 2–3 repeats with full recovery.
• Workout B: High-volume calisthenics day: 8 rounds of 5 pull-ups, 10 push-ups, 15 squats; gradually reduce rest.
• Workout C: Full or near-full Murph attempt with scaled partitioning; note time and recovery needs.

Week 12: Taper and execution

• Workout A: Short interval run and technique checks. Emphasize mobility and light activation.
• Workout B: Light CG (cross-training) and mental rehearsal; sleep and nutrition focus.
• Day of Murph: Warm-up thoroughly: 800m–1 mile easy jog, dynamic mobility, movement-specific activation: banded pull-aparts, scapular pull-ups, 2–3 sets of light push-ups and squats.

Partitioning strategies that work

• 20/40/60 plan: 5 rounds of 20 pull-ups, 40 push-ups, 60 squats — simple and commonly used.
• 10/20/30 plan: 10 rounds of 10 pull-ups, 20 push-ups, 30 squats — keeps reps low per round and more frequent rest.
• Greased groove: Multiple sets of low-rep pull-ups spread throughout the day in the weeks leading up to Murph to increase neurological efficiency.

Pull-up development

• If strict pull-ups are not yet achievable for high reps, use banded pull-ups, jumping negatives, or inverted rows. Focus on eccentric control; lower slowly to build strength.
• Once capable of 10–15 strict pull-ups per set, add volume and perform mid-week high-rep sets to build endurance.

Push-up and squat considerations

• For push-ups, keep the torso aligned, elbows at ~45 degrees, and engage the core. Knee push-ups can be used as a bridge if full push-ups are not yet reliable for high reps.
• Air squats require a full range of motion with hips breaking parallel to protect knees and optimize muscular recruitment. Maintain an upright chest and weight on the heels.

Nutrition and recovery

• Carbohydrate fueling before the workout helps sustain prolonged high-rep efforts. A small, easily digestible carbohydrate-rich meal 60–90 minutes beforehand is a practical choice for many.
• Hydrate adequately in the days leading up to the event and during the workout as needed. Post-exercise, prioritize protein and carbohydrate to promote recovery.

Mental strategies

• Break the workout into small, manageable goals: approach each round as a short mission rather than the entire 600-rep task.
• Establish a cadence for breathing and movement, and use a movement partner or team to maintain pace and morale.
• Focus on consistent tempo rather than ego-based speed, especially early in the workout.

Scaling options and safety considerations

Murph is scalable and can be adapted for beginners, people with injuries, and those who want a shorter or safer version.

Scaling examples

• Reduce total reps by half: 50 pull-ups, 100 push-ups, 150 squats.
• Substitute ring rows for pull-ups or use band-assisted pull-ups.
• Perform push-ups on knees or incline push-ups.
• Replace the 1-mile runs with shorter runs or bike intervals for those with joint or impact concerns.

Weighted vest caution

• Wearing a 20-lb weighted vest is a tradition some participants adopt to echo Murphy’s uniformed load, but it substantially increases load on joints and the cardiovascular system. Athletes should only add weight after proving capacity to complete Murph without it and after acclimating to training with external load.
• If wearing a vest, start with short workouts to build tolerance: try sub-maximal versions with light vests before a full Murph.

Common safety pitfalls

• Sacrificing form for speed increases risk of tendinopathy and acute injury; prioritize controlled movement.
• Rapid, unplanned escalation of volume or intensity can produce overuse injuries, especially in shoulders and elbows from high pull-up volumes.
• Heat illness is a real risk during outdoor gatherings; participants should monitor for dizziness, confusion, or inability to complete the workout safely.

Medical guidance

• Anyone with a known cardiac, respiratory, or musculoskeletal condition should consult a physician before attempting Murph.
• If dizziness, chest pain, or severe shortness of breath occur, stop immediately and seek medical attention.

Stories from the field: what the Murph looks like in practice

The Murph manifests in many formats. In competition-style CrossFit gyms, athletes often attempt the workout individually, timing themselves, and seeking personal PRs. In community events, the focus shifts to participation and remembrance.

The Lt. Michael P. Murphy Museum on Long Island provides a particularly illustrative example. The annual event attracts diverse participants: seasoned athletes aiming to finish as prescribed, service members and veterans who come to mark the holiday, families and neighbors who join a team or take part in scaled formats, and first-time participants who want a meaningful challenge.

Chris Wyllie, who organizes the Long Island Murph and runs the museum, provides the organizational backbone for a ceremony tied to the workout. He emphasized the emotional dimension: many attendees arrive unsure whether they can finish, but the shared environment — with volunteers, fellow participants and onlookers — often pushes them to “another rep or two,” producing a palpable emotional reaction. For many, finishing Murph alongside others becomes a private victory expressed in a public setting.

Elsewhere, hundreds of CrossFit affiliates run Murph classes with live music, ceremonial starts, and fundraising drives for veterans’ charities. Some communities take the workout to parks where teams of neighbors alternate through the workload, turning the event into a civic display of remembrance.

Online, social media amplifies the ritual: photos of chalked hands, weighted vests at sunrise, and sweaty group shots create a seasonal visual shorthand for Memorial Day. That visibility has both expanded participation and turned Murph into an annual calendar marker for many gym-goers.

Cultural impact and the ethics of memorial workouts

Murph’s spread raises questions about how societies remember through embodied acts. The workout reframes remembrance as a physical and communal practice. Critics might ask whether turning grief and memorial into a fitness event risks trivializing sacrifice. Proponents counter that embodied rituals — shared effort and disciplined repetition — have deep roots in human commemorative practice.

Three reasons the Murph resonates across contexts:

1. Embodied remembrance: Performing a strenuous act in honor of the fallen provides an active form of empathy. The discomfort of the workout is symbolically tied to the discomfort of loss and the hardship of service.
2. Community aggregation: Gyms and veteran organizations provide infrastructure for collective participation, which converts individual workouts into civic ritual.
3. Storytelling pipeline: Narrative vehicles such as museums and films relay the story behind the workout, giving participants a face and a name to anchor their effort.

The crossover with mainstream culture — most notably the film Lone Survivor — broadened public awareness of Operation Red Wings and, by extension, Murphy’s story. That exposure created a bridge for non-military communities to engage with military remembrance through fitness.

At the same time, organizers and communities framing Murph events generally emphasize respect: ceremonies, moments of silence, and educational elements about the service member being remembered ensure the workout remains tethered to its commemorative intent.

Training for different athlete profiles: beginners, intermediate, and advanced

Beginners

• Goal: Finish the workout in a scaled format.
• Training focus: Build basic running fitness, develop push-up and squat capacity, and establish a pull-up progression (bands and rows).
• Example approach: Over 8–12 weeks, establish the ability to do multiple sets of 5–10 pull-ups (assisted as needed), 20–30 push-ups per set, and 30–50 squats per set. Practice shorter "mini Murphs" — e.g., 0.5-mile run, 50/100/150 reps.

Intermediate athletes

• Goal: Complete full Murph without a vest, with sensible partitioning.
• Training focus: Increase pull-up volume, practice transitions, and simulate Murph partitioned sets.
• Example approach: Work on 10–15 pull-ups per set and incorporate conditioning runs of 3–5 miles with calisthenic sequences afterward.

Advanced athletes

• Goal: Complete Murph Rx with or without a weighted vest, and target a specific time.
• Training focus: Improve lactate tolerance, high-volume pulling, and vest-specific conditioning if planning to use added weight.
• Example approach: Include high-intensity interval runs, heavy pull-up variations, and progressive vest workouts leading to 1–2 full-weight rehearsals before race day.

No matter the level, emphasize regular recovery: sleep, nutrition, and active rest prevent the chronic fatigue that undermines performance and increases injury risk.

Measuring success: performance, presence, and purpose

Success at Murph should be measured beyond the stopwatch. Performance metrics (total time, pace splits, and rep distribution) matter to some participants. For many others, success takes the form of presence: showing up to honor the fallen, helping a teammate, or completing the challenge after doubt.

Purpose binds performance and presence. The workout’s origin and the events around it place the exertion in a moral frame. Doing Murph becomes a symbolic labor — an act intended to keep memory active by transforming silent remembrance into communal, physical effort. That framing explains why groups opt to host memorial ceremonies alongside the workout: the exercise becomes part of a larger ritual of civic memory.

How organizations and gyms can host a respectful Murph event

Best practices for hosts

• Provide clear guidelines for scaling and safety, including recommended partition strategies and medical resources.
• Include a brief ceremony or moment of silence and, where possible, educational materials about Lt. Michael P. Murphy and other service members being honored.
• Offer team or relay formats for those who cannot complete Murph solo.
• Coordinate hydration and first-aid stations, especially for outdoor events in warm weather.
• Consider fundraising or donation options tied to veterans’ charities or museum maintenance to connect physical effort with tangible support.

Logistics checklist

• Timeline and start time (early morning typically preferred).
• Equipment: pull-up bars or rings, floor space for push-ups and squats, timing equipment.
• Volunteer staff: judges, medical point person, and volunteers to manage transitions.
• Communication plan: pre-event emails or posts with movement standards, warm-up protocols, and parking/location details.

By centering safety and ceremony, organizers ensure the event remains both physically manageable and emotionally resonant.

The Murph and veteran communities: bridging civilians and service members

Murph events often foster interaction between civilian participants and veterans. That interaction serves several functions:

• Mutual respect: Civilians show commitment to memory through physical labor; veterans see the willingness among non-service members to honor sacrifice in a public way.
• Social support: Events create opportunities for veterans to find community and for civilians to gain direct awareness of military experiences.
• Fundraising and advocacy: The gatherings frequently link to organizations that support veterans’ physical, mental, and social health.

Organizers should remain sensitive to veterans’ varied experiences. For some, public displays of remembrance offer comfort. For others, the attention can be complex. Providing optional programming — quiet spaces, veteran-led storytelling sessions, or counseling resources — helps tailor the event to varied needs.

The Murph in numbers and narratives

Participation at memorial Murph events continues to grow. Local gyms report surges in sign-ups at community events, and public spaces filled with participants on Memorial Day morning have become common in many regions. On Long Island, Chris Wyllie’s museum-related event reflected this growth: reported sign-ups rose from 280 one year to 366 the next, with further increases expected. Across the United States and internationally, the workout functions as both a fitness challenge and a public act of remembrance.

Narratives accompanying these events vary. Some attendees seek personal transformation — overcoming physical limits or mental barriers. Others attend to maintain links with family military histories or to mark grief. The diversity of motivations highlights the workout’s adaptable nature: it can be a purely athletic endeavor, a somber tribute, or both.

Addressing common misconceptions about Murph

Myth: Murph is only for elite athletes Reality: The workout scales easily. Many community events offer relay and scaled options to make participation possible for a wide range of fitness levels.

Myth: You must wear a weighted vest Reality: The vest is a tradition some adopt, but it is not required. The core workout itself is demanding without added weight. Athletes should prioritize readiness before adding load.

Myth: Murph is primarily a performance test Reality: For many participants, Murph serves as a commemorative ritual. While timed attempts are common, the purpose of the workout at memorial events is remembrance and collective participation.

Myth: Murph glorifies militarism Reality: Interpretations vary, but participants and organizers typically emphasize honor, sacrifice, and public memory rather than political messaging. Events often include educational or charitable elements to ground the workout in service and support.

FAQ

Q: Who created the Murph and why is it named that? A: The workout was devised by Lt. Michael P. Murphy and fellow trainee Kaj Larsen during SEAL training. The name "Murph" honors Lt. Murphy, who was killed in 2005 while performing an act of conspicuous bravery during Operation Red Wings. The workout now functions as both a fitness challenge and a memorial tradition.

Q: What exactly is the Murph? A: Standard Murph consists of a 1-mile run, 100 pull-ups, 200 push-ups, 300 air squats, and a finishing 1-mile run. Athletes commonly partition the pull-ups, push-ups and squats into multiple rounds to maintain effort and form.

Q: Is wearing a weighted vest required? A: No. Wearing a weighted vest is a tradition some participants adopt to honor service members who wear body armor. It significantly increases the difficulty and risk of the workout; athletes should only add weight after establishing competence with the unweighted Murph.

Q: How should I train if I have no pull-up ability? A: Start with assisted pull-up variations — bands, ring rows, or inverted rows — and emphasize eccentric (lowering) strength. Build volume gradually. Incorporate frequent low-rep max efforts (greased-groove style) to develop neurological efficiency.

Q: Can Murph be scaled for beginners or people with injuries? A: Yes. Scaled formats include halving the rep scheme (50/100/150), using ring rows or banded pull-ups, performing knee or incline push-ups, and substituting biking or short runs for the 1-mile segments. Team formats can distribute reps across members.

Q: How long does Murph take? A: Completion times vary widely. Advanced athletes may finish within 30–45 minutes; many participants finish between 45 and 90 minutes depending on pacing, scaling, and rest. Focus on safe completion rather than an arbitrary time goal, especially if the event emphasizes memorial intent.

Q: What should I eat and drink before attempting Murph? A: Consume a small, carbohydrate-focused meal 60–90 minutes before the workout to provide accessible energy. Hydrate well in the days leading up to the event. Avoid heavy, high-fat meals immediately before exertion. Tailor intake to personal tolerance.

Q: Is Murph appropriate for group events and community memorials? A: Yes. Many gyms, veteran organizations, and local groups use Murph as a community memorial event. Organizers should emphasize safety, inclusivity, and ceremony elements (moment of silence, educational materials) to maintain the event’s commemorative purpose.

Q: How do I balance performance goals with honoring the fallen? A: Determine your personal intent before the workout. If honoring is primary, consider joining a team, focusing on completion and presence rather than speed, and participating in any memorial components. If performance is primary, still respect ceremony elements and the event’s purpose.

Q: Where can I learn more about Lt. Michael P. Murphy’s life and legacy? A: Museums, veteran organizations, and authorized biographies provide context about Lt. Murphy’s life and service. Local events tied to his name, such as those hosted by the Lt. Michael P. Murphy Museum, often include educational content and commemorative programming.

The Murph Challenge occupies a distinctive place where physical exertion, memory, and community intersect. Whether approached as a test of fitness, a way to honor a fallen comrade, or both, the workout demands preparation and respect. For those who take it on, the experience is rarely only physical: participants return with an awareness that a grueling set of reps can also be a vessel for remembrance, and that shared hardship remains one of the oldest forms of communal tribute.
