What change is recommended when moving from indoor 60 m to outdoor 100 m seasons?

• A. Keep the indoor plan unchanged.
• B. Reduce the emphasis on longer accelerations.
• C. Add longer accelerations, top-speed, and speed-endurance work; adjust volume for longer distance and outdoor conditions.
• D. Focus exclusively on sprint starts.

Answer: (C)

Moving from indoor 60 m to outdoor 100 m changes the race demands from a quick, almost pure acceleration event to one that requires sustaining high speed for a longer distance. The best approach is to add longer accelerations, top-speed work, and speed-endurance work, and adjust volume to fit the longer distance and outdoor conditions. Longer accelerations help ensure you reach your true top speed earlier and can maintain momentum as the race progresses. Top-speed work builds the velocity you need to hold through the middle and late portions of the 100 m, while speed-endurance work trains your body to maintain high speed under fatigue across the full distance. Outdoor conditions—longer race distance, wind, surface differences—also justify increasing overall training volume and tailoring it to outdoor racing realities.

Other options fall short because they don’t prepare the athlete for the 100 m’s extended high-speed phase: keeping the indoor plan unchanged under-trains the longer demands, reducing emphasis on longer accelerations misses a crucial part of reaching and sustaining top speed, and focusing only on sprint starts neglects acceleration quality into the full race and the endurance needed to finish fast.
