Workout Description

Why This Workout Is Medium

This workout is a tempo/pacing challenge rather than a strength or skill test. The 40-second rest between 180m runs (roughly 60-90 seconds of work for average athletes) provides adequate recovery, keeping heart rate manageable. The 3-minute break between sets allows substantial recovery. The primary demand is aerobic capacity and running consistency, not extreme intensity. Most average CrossFitters can complete as prescribed, though pacing strategy becomes important to maintain consistent splits across all 10 rounds.

Training Focus

This workout develops the following fitness attributes:

• Speed (9/10): This is a speed-focused workout emphasizing quick leg turnover and fast cycling. Minimizing transition time and maintaining high velocity across all ten rounds is critical for optimal scoring.
• Endurance (8/10): Ten 180m repeats with minimal rest (40s) demands sustained cardiovascular output. The 3-minute break between sets allows partial recovery but overall aerobic capacity is heavily tested throughout.
• Stamina (7/10): Repeated running efforts with short recovery periods challenge muscular endurance in the legs. The cumulative fatigue across ten rounds tests sustained lower body output and mental toughness.
• Power (6/10): Each 180m repeat requires explosive leg drive and acceleration, particularly at the start of each round. Power output directly influences split times and overall performance.
• Flexibility (2/10): Basic range of motion needed for running mechanics. No extreme mobility demands; standard hip and ankle flexibility sufficient for efficient running form.
• Strength (1/10): Running requires minimal force production compared to loaded movements. No external resistance or maximal effort strength demands present in this workout.

Scaling Options

For beginners or athletes with limited sprint capacity, reduce distance to 120-150m per rep and extend rest to 60 seconds between reps. Keep the 3-minute break between sets intact — that structure is essential. If a 180m outdoor or track surface isn't available, substitute with a 200m row or a 20-calorie Assault Bike sprint as a distance-equivalent option that preserves the short-burst, high-intensity demand. Reduce to 4 rounds per set (4x instead of 5x) if maintaining sprint quality across all 10 reps is not realistic. Athletes with lower limb injuries can substitute on the Ski Erg for a 30-second max-effort pull per rep.

Scaling Explanation

Scale if your times are degrading by more than 5-6 seconds from your fastest to slowest rep — this signals that the rest interval is insufficient for your current fitness level and you're working in a hole that defeats the sprint stimulus. The goal is to preserve QUALITY sprints, not just survive intervals. If you cannot run at above 85% perceived effort on every rep, increase rest or reduce distance. Prioritize maintaining sprint mechanics and true high-intensity output over hitting the prescribed distance or rest scheme. Athletes newer to sprint work should lean toward the 120m distance and 60-second rest to build the aerobic buffer and sprint pattern before progressing to the full prescription.

Intended Stimulus

This is a pure sprint interval session targeting your phosphocreatine and anaerobic glycolytic systems. Each 180m rep should feel like a true sprint — short burst, maximal power output lasting roughly 25-45 seconds depending on fitness level. The 40-second rest is intentionally short to create meaningful fatigue while the 3-minute break between sets allows partial recovery, exposing the difference between fresh-sprint speed and fatigued-sprint speed. The primary challenge is mental discipline: committing to full effort on every rep despite accumulating fatigue, and resisting the temptation to pace early. This builds speed endurance, teaches your body to clear lactate quickly, and sharpens your ability to hold mechanics under respiratory distress.

Coach Insight

Track every single rep with a stopwatch — this is non-negotiable since your score depends on accuracy. Aim for near-identical splits across all 10 reps; a consistent average beats heroic early efforts followed by a collapse. Start the first set at about 95% effort rather than an all-out sprint — save the true max for reps 8-10 when you want to prove your fitness. Drive your arms hard and stay tall through the hips — slouching kills speed and wastes energy. Breathe aggressively during the 40-second rest; get your hands off your knees, stand upright, and take deep controlled breaths to recover faster. The 3-minute break is your window to shake out your legs and mentally reset. Common mistake: going out too hot on rep 1 and dying in the second set — if your second set times are 5+ seconds slower than your first, you went too fast. Aim for a time drop of no more than 2-3 seconds between your best and worst rep.

Benchmark Notes

Pure running speed and aerobic capacity are the limiters; the 40s rest is short enough that lactate accumulates across sets and the 3-min break only partially clears it. L5 (~47s average per 180m) reflects a typical CrossFitter running at roughly 4:20/km pace under cumulative fatigue.

Modality Profile

Run is a cyclical cardio movement classified as Monostructural (M). With only one movement in the workout, it comprises 100% of the modality profile.
