Workout Description

Why This Workout Is Medium

For the average CrossFit athlete, CrossFit Games 21.3 is Medium: the movement is accessible, but racing roughly 4:00 makes pacing and sustained output the challenge. There is no movement interference or technical load to manage, so difficulty comes from holding an aggressive split without fading. The athlete can scale distance or pace while preserving the same monostructural test.

Training Focus

This workout develops the following fitness attributes:

• Endurance (7/10): CrossFit Games 21.3 scores 0.7 for endurance because its 4:00 domain and monostructural share demand sustained aerobic output. Breathing control still determines how consistently the athlete can execute the full prescription.
• Speed (7/10): The 4:00 scoring window and 1 movement score 0.7 for speed; success rewards repeatable cycling, decisive transitions, and appropriately aggressive pacing.
• Stamina (2/10): The repeated work around Run scores 0.2 for stamina; athletes must preserve local muscular output as sets, rounds, and transitions accumulate fatigue.
• Strength (1/10): Force and control demands score 0.1 for strength. Strength supports posture and movement quality, while absolute load is either unreported or not the workout's primary scoring challenge.
• Flexibility (1/10): The prescribed positions create a 0.1 flexibility demand: efficient range of motion matters, but mobility is supportive rather than the sole test.
• Power (1/10): Run drive a 0.1 power score through controlled force rather than maximal explosiveness. Explosive intent must remain repeatable rather than deteriorating into slow, inefficient repetitions.

Movements

• Run

Scaling Options

Reduce the distance to roughly 70-80%, use a same-duration effort on another monostructural machine, or complete the prescribed course at a controlled training pace.

Scaling Explanation

Keep the athlete in the short, high-output domain while preserving uninterrupted cyclical work. The correct scale ends with a strong finish, not a long survival shuffle.

Intended Stimulus

CrossFit Games 21.3 is a short, high-output monostructural test of pacing and sustainable output. The athlete should settle quickly at the fastest honest pace for the full course, then finish with a controlled acceleration instead of fading after an overaggressive start.

Coach Insight

Choose the opening split before starting, stay mechanically relaxed through the middle, and increase cadence only when the remaining distance is genuinely sustainable. Avoid surging early or letting technique shorten as fatigue rises.

Benchmark Notes

L5 is anchored near 1:45 for an average Rx athlete, allowing realistic set breaks and transitions around Run. L10 targets 1:03 with deliberate pacing, near-unbroken skill work, and minimal transition loss.

Modality Profile

Counting each unique movement once, M includes Run. That produces G 0%, M 100%, and W 0%.
