The basic endurance drills used in military training are 8 standardized conditioning exercises — the 30:60s, 60:120s, formation runs, hill repeats, ability group runs, sustained airborne run, terrain run, and Fartlek run — all designed to build the cardiovascular base soldiers need for combat. They prioritize sustained aerobic capacity over speed, and stack progressive intensity over weeks. The drills appear in the U.S. Army’s Field Manual 7-22 as the foundation of soldier conditioning.
This guide breaks down each of the 8 drills, what they target, how to perform them at home or on a track, the 6-week progression to build a military-grade aerobic base, and how to integrate the drills with bodyweight strength training.
Why endurance is the foundation of military fitness
Combat is endurance under load. A soldier carrying 60+ lb of gear over varied terrain for hours doesn’t need elite speed — they need a heart and lungs that can sustain effort for 60+ minutes without breaking. Strength matters; endurance keeps you alive.
According to the U.S. Army’s Field Manual 7-22, all soldier conditioning starts with the aerobic base. Strength, sprint, and tactical drills build on top of it.
The 8 core military endurance drills
1. The 30:60 drill
30 seconds sprint, 60 seconds walk. Repeat 6–10 rounds. Builds VO2 max and recovery between efforts.
2. The 60:120 drill
60 seconds run at moderate-hard pace, 120 seconds walk. Repeat 5–8 rounds. Bridges the gap between sprint and steady-state.
3. Formation run
Group run at conversational pace, 2–4 miles. The standard “long, slow distance” base-building session.
4. Hill repeats
Find a hill that takes 60–90 seconds to climb at hard effort. Run up hard, walk down. 6–10 repeats. Builds leg strength + lung capacity simultaneously.
5. Ability group run (AGR)
Soldiers grouped by current 2-mile time. Each group runs at its target race pace for 1–2 miles. At home, this looks like running at your goal pace for shorter distance.
6. Sustained airborne run
Continuous run at slightly elevated pace for 4–6 miles. Used to build the duration capacity airborne units need.
7. Terrain run
Run on uneven ground — trails, sand, grass — for 2–4 miles. Strengthens stabilizers and ankles for real-world conditions.
8. Fartlek run
“Speed play” — randomly alternate sprint, jog, and walk for 20–30 minutes. Builds the ability to handle unpredictable effort changes.
6-week home progression
Week 1–2: Build base
- Mon: 30:60 drill — 6 rounds
- Wed: Formation run — 2 miles easy pace
- Fri: 60:120 drill — 5 rounds
- Sat: Long run — 3 miles
Week 3–4: Add intensity
- Mon: 30:60 — 8 rounds
- Tue: Hill repeats — 6 reps
- Thu: Tempo run — 2 miles at hard but sustainable pace
- Sat: Long run — 4 miles
Week 5–6: Peak
- Mon: 30:60 — 10 rounds
- Wed: Fartlek — 25 minutes
- Thu: Hill repeats — 8 reps
- Sat: Long run — 5 miles + terrain
Pair this with 3 days/week of bodyweight strength training. Our military calisthenics workout provides the strength side of the program.
Military endurance benchmarks
- Army 2-mile run: sub-15:00 to score 90 points (good); sub-13:30 for elite.
- Marine 3-mile run: sub-21:00 to score max points (women: sub-22:00).
- Navy 1.5-mile run: sub-11:00 for high score.
- Special Forces 5-mile run: sub-40:00 expectation; sub-35:00 elite.

FAQ
Can I do these drills without a track?
Yes — the 30:60 and 60:120 drills work anywhere with a flat space. Time-based intervals don’t require a measured course. A neighborhood, park, or treadmill all work.
How is this different from regular running?
Standard running often plateaus because pace stays constant. Military drills mix steady-state, intervals, hills, and unpredictable terrain — building both VO2 max and the muscular endurance required for tactical work.
Should I add a weighted vest or rucksack?
Only after 6+ weeks of unweighted base. Add 15–20 lb to formation and terrain runs first; never add weight to sprint drills (injury risk).
How often should I run?
3–5 days per week for serious conditioning. Beginners start at 3, advanced at 5. Always include 1–2 rest or cross-training days.
Can these drills replace HIIT?
The 30:60 and 60:120 drills are HIIT — military versions of the same protocol. They tend to be longer in duration and more pace-flexible than gym HIIT classes.
The bottom line: military endurance drills stack three qualities — aerobic base, anaerobic capacity, and terrain-handling — that civilian running rarely combines. Six weeks on the protocol above will measurably improve your 2-mile time, your VO2 max, and your ability to hold pace under fatigue. Pair with bodyweight strength work via our military calisthenics plan for full conditioning.
