Air Force HAMR Shuttle Standards: 20m Beep Conversion Table
Official scoring matrices, level progression, and shuttle conversion targets for the 20-meter HAMR under DAFMAN 36-2905 and AF Form 4446.
The 20-meter High Aerobic Multi-shuttle Run (HAMR) is an authorized cardio alternate to the 2-mile run on the Air Force PFRA. Cardio is worth 50 points with a 35-point minimum. To earn the maximum 50 cardio points, airmen under 25 must complete 87 shuttles (42 shuttles is the 35-point minimum), while female airmen under 25 must complete 68 shuttles (21 shuttles is the 35-point minimum).
You can check how your HAMR shuttles combine with your push-up and core scores using our Air Force PFRA calculator to see your composite tier.
Official HAMR Shuttle Scoring Tables by Age and Gender
The HAMR evaluates maximal aerobic velocity through 20-meter back-and-forth sprints paced by standardized audio cues. Cardio is worth 60% of the total 100-point PFA composite:
| Age Cohort | Male Min Pass (35 Pts) | Male 50-Pt Target | Male Max (60 Pts) | Female Min Pass (35 Pts) | Female 50-Pt Target | Female Max (60 Pts) |
|---|---|---|---|---|---|---|
| Under 25 | 50 shuttles | 78 shuttles | 100 shuttles | 35 shuttles | 60 shuttles | 80 shuttles |
| 25 to 29 | 48 shuttles | 75 shuttles | 97 shuttles | 33 shuttles | 57 shuttles | 77 shuttles |
| 30 to 34 | 45 shuttles | 71 shuttles | 92 shuttles | 31 shuttles | 54 shuttles | 73 shuttles |
| 35 to 39 | 41 shuttles | 66 shuttles | 86 shuttles | 28 shuttles | 50 shuttles | 68 shuttles |
| 40 to 44 | 37 shuttles | 61 shuttles | 80 shuttles | 25 shuttles | 45 shuttles | 62 shuttles |
| 45 to 49 | 32 shuttles | 55 shuttles | 73 shuttles | 22 shuttles | 40 shuttles | 56 shuttles |
| 50 to 54 | 27 shuttles | 49 shuttles | 65 shuttles | 19 shuttles | 35 shuttles | 50 shuttles |
| 55+ | 22 shuttles | 42 shuttles | 57 shuttles | 16 shuttles | 30 shuttles | 43 shuttles |
HAMR Course Setup and Audio Cadence Rules
The HAMR is administered under strict environmental and timing protocols:
- Course Geometry: Two parallel lines marked exactly 20.0 meters apart on a flat, non-slip indoor gymnasium hardwood or composite surface. Outdoor grass setups are prohibited.
- Audio Pacing: The official USAF audio track plays continuous electronic beeps. The interval between beeps starts slowly (8.5 km/h) and accelerates automatically by 0.5 km/h at each successive level (roughly every 60 seconds).
- Foot Placement Standard: The airman must touch the 20-meter line with at least one foot on or before the sounding of the beep, pivot, and sprint back. Turning before touching the line is a fault.
- Two-Fault Elimination Rule: If an airman fails to touch the line before the beep sounds, they receive one warning and must immediately sprint to catch the pace. A second failure to beat the beep at any point terminates the test. The score recorded is the last successfully completed shuttle.
Pacing Strategy: HAMR vs. 1.5-Mile Run
Many airmen choose the HAMR because it avoids adverse weather conditions (wind, extreme cold, or rain) and requires less total running volume (under 1.25 miles even for a max score). However, the frequent 180-degree deceleration and acceleration puts higher demands on ankle stability and groin adductors. When pivoting at the line, alternate your lead pivot foot between laps to distribute muscular fatigue evenly across both legs.
Cardio is half the PFRA composite, so pair it with the cross-leg reverse crunch standards.
