Workout Description

Why This Workout Is Hard

While running is simple and requires no technical skill, the context makes this challenging. Running 100m in 16-24 seconds requires near-sprint effort, and only 10 seconds rest between rounds creates a brutal work-to-rest ratio (roughly 2:1). This inadequate recovery causes massive oxygen debt accumulation—by rounds 5-6 of each set, maintaining pace becomes extremely difficult. The 3-minute rest provides recovery before repeating, but 16 total sprint efforts with minimal rest is significant cardiovascular punishment for the average athlete.

Training Focus

This workout develops the following fitness attributes:

• Speed (9/10): The primary stimulus is sprinting at near-maximal velocity repeatedly, testing pure speed and the ability to maintain high-velocity output with minimal rest.
• Power (8/10): Each 100-meter sprint at 16-24 seconds is an explosive, high-intensity anaerobic effort requiring significant power output and fast-twitch muscle recruitment.
• Stamina (7/10): Sixteen total 100-meter efforts challenge the legs' ability to maintain sprint output despite accumulating fatigue, testing anaerobic stamina and repeated sprint capacity.
• Endurance (6/10): Repeated sprint intervals with minimal rest (10s) create significant cardiovascular demand and test the anaerobic-aerobic interface, though the 3-minute rest between sets provides recovery.
• Strength (1/10): Bodyweight running requires minimal maximal strength; this is not a strength-focused workout.
• Flexibility (1/10): Basic running mechanics require only fundamental range of motion with no significant mobility demands.

Scaling Options

Reduce distance to 75m or 50m to maintain target time of 16-24 seconds at high intensity. Consider 6 reps per set instead of 8 if unable to maintain pace. If running causes pain, substitute 15/12 calorie assault bike or 200/150m row per interval. Extend rest to 15-20 seconds only if athlete is completely unable to continue moving at speed. Priority is preserving sprint intensity over completing prescribed distance.

Scaling Explanation

Scale if pace drops below 30 seconds per 100m or if you're reduced to a jog/shuffle. The workout loses its intended stimulus if intensity drops too low. Better to run 50m at 90% effort than 100m at 60% effort. Athletes should finish each rep breathing hard but able to run again in 10 seconds. If you can comfortably hold conversations during rest periods, increase distance. Target feel is 8-9/10 effort by final reps of each set.

Intended Stimulus

High-intensity sprint intervals targeting anaerobic capacity and speed endurance. Each 100m should take 16-24 seconds, placing primary demand on the glycolytic energy system with phosphagen support. The 10-second rest creates incomplete recovery, forcing athletes to maintain power output under accumulating metabolic stress. This develops repeat sprint ability and mental resilience to work at high intensity when fatigued.

Coach Insight

Start conservatively at 75-80% max effort on reps 1-2. The short rest means fatigue accumulates rapidly - most athletes crash on reps 5-6 of the first set. Focus on fast leg turnover and maintaining stride length as fatigue builds. Use the 10 seconds to walk back to start, shake legs out, and reset breathing. The 3-minute break will feel insufficient - expect the second set to be significantly harder both physically and mentally. Resist the urge to coast early thinking you're saving energy. Consistent pacing across all 16 sprints is the goal.

Benchmark Notes

Primary limiter is anaerobic capacity and the ability to resist speed decay with minimal rest. L1 (704s) averages ~24s per 100m with moderate slowdown. L5 (640s) averages ~20s per 100m, maintaining pace in the prescribed 16-24s window. L10 (480s) averages ~15s per 100m, demonstrating elite repeated sprint ability with only 10s recovery. Athletes must manage pacing strategy—going out too fast will cause significant drop-off in the second set after the 3-minute rest. The short recovery intervals make this a true test of sprint repeatability rather than pure top-end speed.

Modality Profile

Run is a cyclical cardio movement classified as Monostructural (M). With only one movement in the workout and that movement being purely monostructural, the modality breakdown is 100% Monostructural.
