How to run a faster 2 -Mile for the Air Force Physical Fitness Readiness Assessment

The 2-mile run is the primary measure of cardiorespiratory fitness for the Air Force Physical Fitness Readiness Assessment.

The 2-mile run tests your aerobic endurance – your body’s ability to use oxygen efficiently during prolonged physical effort. The 2-mile run isn’t just about passing a fitness assessment; it’s about building the stamina needed for military readiness.

Training to run faster is most effective when utilizing the following core training principles:

• Progressive Overload: Gradually increase workout intensity and volume. Too much overload too soon leads to musculoskeletal injury.
• Specificity: Train according to the goal. Focus on runs that mimic the 2-mile run’s demands. Running is more effective for improving 2-mile run score than cycling.
• Variety: Use different workouts to target endurance, speed, and lactate threshold conditioning.
• Recovery: Include rest days to let your body adapt and grow stronger. Do not ignore recovery because your body can only improve if it has time to rebuild.
• Consistency: Stick to the plan for steady improvement.

Running faster isn’t just about pushing yourself harder- it’s about training smarter. Brandon Powers, 88th Air Base Wing Operational Support Team strength and conditioning specialist, offers the following training tips to build endurance, improve speed, lower injury risk, and run faster on your 2-mile run.

1. Develop the base fitness foundation with consistent, moderate-effort running workouts

Powers advises Airmen to ease into hard running workouts. “Increase running volume slowly to avoid overuse injuries like shin splints,” states Powers.

For an Airman returning to running after being off 4+ weeks, Powers recommends a walk-to-run program. A walk-to-run program gradually builds running stamina by alternating intervals of walking and jogging, typically starting with 1–2-minute jogs and longer walking recovery over 8 weeks. This method reduces injury risk, improves endurance, and allows an Airman to comfortably reach 20-30 minutes of continuous running.

2. Utilize different types of run training methods to build endurance, improve speed, and

enhance lactate threshold. “A good training regimen should include long slow distance, interval training, and continuous sustained effort conditioning,” states Powers.

Long Slow Distance runs (LSD) build endurance, improves cardiovascular efficiency, and strengthens muscles and joints to handle the stress of high-volume running.

“The intensity of LSD work is low to moderate, so your pace should feel relatively easy and relaxed,” states Powers. To establish the appropriate training intensity, aim to workout at         55-75% of your maximum heart rate (maximum heart rate = 220 -your age).

To calculate Target Heart Rate Training Zone for a 25 -year-old:  

1. Determine Maximum Heart Rate (MHR): 220-25= 195 beats per minute (bpm)
2. LSD Target Heart Rate Zone: 55-75% of MHR
3. LSD lower zone: 55% of MHR: 195 x 0.55 = 107 bpm
4. LSD upper zone: 75% of MHR: 195 x 0.75= 146 bpm
5. Target Heart Rate Zone: 107 bpm-146 bpm.

How to measure:

• Manual pulse: Count beats on your wrist (radial artery) or neck (carotid artery) for 30 seconds and multiply by 2, or count beats for 10 seconds and multiply by 6.
• Wearable devices: Use smartwatches or chest strap monitors.

Knowing your target heart rate helps you pace your workouts. Exercising at the right level of intensity will help you avoid burning out or wasting time with a workout that’s not vigorous enough to help you meet your goals.

When you first start training, aim for the lower bpm number for your age range. As you get fitter, you can slowly work towards the higher number.

If you don’t have access to heart rate monitoring, you can use the Rating of Perceived Exertion (RPE) scale to gauge your intensity. RPE is a subjective measure to use for a single effort. On a scale of 1-10, with 10 being the greatest effort, the LSD workout should feel like a 5.

For LSD workouts, focus more on duration than intensity. Powers recommends that the LSD training schedule start with 20 min runs at a comfortable pace for weeks 1-2, progressing to 30-40 minute runs for weeks 5-6. Goal is 30-40 minutes of easy activity.

Practicing running faster for specific periods or distances is key to improving your 2-mile run time. Interval training alternates short, intense work intervals with periods of recovery.

“Interval training improves running speed by conditioning your body to adapt to training intensities higher than your normal LSD running pace,” states Powers.

The desired training effect from the short bursts of intense running activity is to get your heart, lungs and active muscles acclimated to exercising at a higher level, which makes it easier for you to do more work at the elevated training level over time.

When performing interval training, the work interval (fast run) is followed immediately by an active recovery interval (walk). An appropriate work-to-recovery ratio for improving speed is 1:2. For example, during the work (run) interval, you will run at a brisk pace for 30 seconds. During the recovery (walk) interval you will walk for 60 seconds. Completing the 30 second run and 60 second recovery is one repetition.

Powers offers an example of a basic interval workout to improve running speed:   

• 10-minute warm-up with walk/light jog, dynamic warm-up/movement preparation.
• Start intervals- Run at a brisk pace for 30 seconds.
• Recover for 60 seconds by slowing down to an easy jog or a walk.
• Repeat run interval-30 seconds/recovery interval-60 seconds for 3-4 repetitions.
• 10-minute cooldown- walk/stretches

Interval training is not about sprinting. A targeted speed that you can maintain in all repetitions through the total workout is most important. The difficulty lies not in a single repetition, but in a series of repetitions. Work on consistency, trying to keep little variation between your fastest and slowest interval and pacing yourself to be fastest at the end of the workout.

Prior to beginning an interval training program, an Airman should establish a foundational conditioning level of fitness. The base level is consistent running activity for several weeks (2-3 times a week for 20 minutes of LSD running). The base fitness level will prepare your muscles and joints for the increased intensity of interval training.

Powers advises that when starting interval training, an Airman should prioritize safety by gradually easing into the workouts to avoid overtraining and injury. Begin with shorter, less intense intervals and progressively increase the intensity and duration as your fitness improves.

Tempo/threshold runs are workouts designed to improve your lactate threshold- the intensity at which lactic acid begins to accumulate in your blood faster than your body can clear it.

You can increase the threshold at which lactate builds up in your bloodstream with tempo/threshold runs. That means you can go faster for longer, without getting worn out.

Powers recommends a tempo/threshold run should be performed at a “comfortably hard” pace. The workout should be demanding but not totally exhausting. On the Rating of Perceived Exertion Scale of 1-10, with 10 being the greatest effort possible, the workout should feel like

6-8. These sessions typically involve running for 6-8 minutes without stopping at a pace approximately 90% of the maximal pace you could hold for that duration.   

When starting tempo/threshold workouts, 2-3 repetitions of 6-8 minutes is sufficient. As fitness levels improve, interval repetitions and duration per workout increase. When performing  tempo/threshold runs, allow sufficient recovery between repetitions so you can maintain the desired intensity of 90% of maximal pace. A reasonable recovery period is approximately half of the work time. During this time, keep moving at a low intensity- slow jog or brisk walk. Do not come to a complete stop.

Keep a record of your training. Record basic information such as time and distance for run workouts including individual times for each interval. A tangible record of your performances allows you to establish specific goals and can increase your motivation to train. Training records make it easier to avoid training mistakes or recognize potential problems before they become serious.
