The HAMR Is a Pacing Test Wearing a Sprint Costume
The 20-meter High Aerobic Multi-shuttle Run looks like a sprint drill, but scores are decided by efficiency in the early levels and the turns. Every length has a built-in pace: the beep. Energy you spend sprinting ahead, turning wide or re-accelerating from a dead stop is taken from the levels where you actually need it. For shuttle-to-points conversion, levels and the practice player, see the HAMR standards and converter; this page is about buying more shuttles with the fitness you already have.
Know the Rules That Decide Your Score
Technique only pays if it keeps you inside the rules. The administrator reads these to everyone before the test (AFMAN 36-2905, Attachment 2):
- Touch the line with one foot before the beep. If you are early, wait for the beep before you start back ¶A2.9.3.
- Late to the line, or leaving it too early, is a warning. Three consecutive warnings end the test; reaching the line on the next shuttle resets the count to zero ¶A2.9.4.
- If the beep beats you, finish that shuttle before turning. Stopping short and turning back, or resting or skipping a shuttle, ends the test ¶A2.9.5.
- Your score is the last successful shuttle completed before three consecutive warnings, or before you stop ¶A2.9.6. One late shuttle is not the end: make the next one and you are back to zero warnings.
The full rules, a worked example and the course requirements are on the HAMR rules section.
The Four Technique Rules
Arrive just before the beep
- What to Do
- Pace each length to touch the line a step early, then leave on the beep (AFMAN 36-2905 para. A2.9.3)
- What It Saves
- No late-arrival warnings, and no sprint-then-stand cycles that drain the tank
Pivot, don't loop
- What to Do
- Plant on the line, drop hips, push off low; no rounded turns
- What It Saves
- A fraction of a second and less braking force, on every length
Alternate plant legs
- What to Do
- Switch which leg plants at each end
- What It Saves
- Shares the fatigue; protects calves and ankles late in the test
Accelerate out low
- What to Do
- First two steps out of the turn stay low and short
- What It Saves
- Reaches pace without the tall-posture lunge that wastes energy
| Rule | What to Do | What It Saves |
|---|---|---|
| Arrive just before the beep | Pace each length to touch the line a step early, then leave on the beep (AFMAN 36-2905 para. A2.9.3) | No late-arrival warnings, and no sprint-then-stand cycles that drain the tank |
| Pivot, don't loop | Plant on the line, drop hips, push off low; no rounded turns | A fraction of a second and less braking force, on every length |
| Alternate plant legs | Switch which leg plants at each end | Shares the fatigue; protects calves and ankles late in the test |
| Accelerate out low | First two steps out of the turn stay low and short | Reaches pace without the tall-posture lunge that wastes energy |
Practice all four with two cones 20 meters apart and the free HAMR practice player: it plays the beeps in your browser, calls out the levels and tracks warnings the way A2.9.4 counts them. Turns are a skill: rehearse them at the easy early levels so they are automatic by the time the beeps get fast.

| Session | Week 1 | Week 6 |
|---|---|---|
| Day 1 | 4×200 m (60 s rest), 2×400 m (75 s rest), 3×30 m sprints | 6×200 m sprints (60 s rest), 4×400 m sprints (75 s rest), 3×30 m sprints (60 s rest) |
| Day 2 | 20 min sustained run, 5×100 m strides, 2×200 m sprints (60 s rest) | 30 min sustained run, 8×100 m sprints with walk-back recovery, 4×200 m (60 s rest) |
| Day 3 | Test your HAMR, then 4×20 m sprints (30 s rest) | Test your HAMR, then 6×20 m sprints (30 s rest) |
For the weekly HAMR test, run the practice player and save each result to its history, then check what it scores with the shuttle converter.
HAMR vs. 2-Mile: Choosing Your Cardio Event
A steady distance runner
- Likely Better Event
- 2-Mile Run
- Why
- Even-pace aerobic output is exactly what the run rewards
Fast but fade over distance
- Likely Better Event
- HAMR
- Why
- Early levels are cheap; speed buys the late levels
Coming back from lower-body injury
- Likely Better Event
- Test both carefully
- Why
- Shuttle turns load ankles and knees differently than steady running
Testing at 5,250 ft or higher
- Likely Better Event
- Either, with the correction
- Why
- Table A3.4 adds 1–4 shuttles to a HAMR score; Table A3.1 lists run-time corrections (AFMAN 36-2905 para. 3.15.12.3)
| You are… | Likely Better Event | Why |
|---|---|---|
| A steady distance runner | 2-Mile Run | Even-pace aerobic output is exactly what the run rewards |
| Fast but fade over distance | HAMR | Early levels are cheap; speed buys the late levels |
| Coming back from lower-body injury | Test both carefully | Shuttle turns load ankles and knees differently than steady running |
| Testing at 5,250 ft or higher | Either, with the correction | Table A3.4 adds 1–4 shuttles to a HAMR score; Table A3.1 lists run-time corrections (AFMAN 36-2905 para. 3.15.12.3) |
Then decide with data, not preference: run both in practice two weeks apart, put both results into the HAMR vs 2-mile comparison, and take the higher-scoring event into the mock PT test to confirm your full-test readiness. If the 2-mile wins, its training plan is here.
Frequently Asked Questions
How does the HAMR shuttle run work?+
You run 20-meter lengths between two lines in time with a recorded beep that gets faster at each level. Touch the line with one foot before each beep, and leave on the beep (AFMAN 36-2905 para. A2.9.3). Missing the line or leaving early is a warning, three consecutive warnings end the test, and your score is the last successful shuttle you completed before them or before you stopped (paras. A2.9.4–A2.9.6). The chart counts shuttles, one per 20 m length, and converts them to up to 50 points by age group and sex.
Should I choose the HAMR or the 2-mile run?+
You can take either cardio option at each test: the AFMAN lists both (AFMAN 36-2905 para. 3.1.2.4), you complete one option per component (para. 3.15.8), and the Air Force confirmed on 6 January 2026 that Airmen may choose either every six months (af.mil). Steady-pace endurance runners usually score better on the 2-mile; athletes with good speed, agility and recovery between efforts often score better on the HAMR. The reliable way to decide is to test both in practice and compare the points each earns for your age group.
What wastes the most energy on the HAMR?+
Two things: overshooting the line (running through it at speed) and wide, upright turns. The rule is to arrive just before the beep with one foot touching the line, then wait for the beep before you leave (AFMAN 36-2905 para. A2.9.3). In the early levels the pace is slow, so settle into a stride that gets you there a step early rather than sprinting, stopping and standing.
How should I turn on the shuttle run?+
Plant one foot on the line (it has to touch the line before the beep), drop your hips, pivot, and push off low on the beep. Alternate your plant leg between lengths to share the load. A good pivot turn saves a fraction of a second and real energy on every shuttle, and over 60 or more shuttles that decides your score.
How do I train for the HAMR specifically?+
Aerobic base still rules: the easy-run volume that improves your 2-mile also raises your HAMR ceiling. The Warfighter's Fitness Playbook 2.0 (Feb 2026) includes a 6-Week HAMR Improvement Program with 200 m and 400 m repeats, a sustained run with strides, and a weekly HAMR test with 20 m sprints. Practising to the beep teaches the rhythm; the free practice player on the HAMR standards page plays the beeps in your browser.
Does altitude affect HAMR scoring?+
Yes, at 5,250 feet or higher (AFMAN 36-2905 para. 3.15.12.3). Table A3.4 adds shuttles to your score: 1 for Group 1 (5,250–5,500 ft), 2 for Group 2 (5,500–6,000 ft), 3 for Group 3 (6,000–6,600 ft) and 4 for Group 4 (above 6,600 ft). The chart itself does not change. Your FAC knows which group your course is in.
