Most distance running coaches know that training for a 5-kilometer race involves a mix of aerobic and anaerobic workout sessions that will adaptively lead to improvements in a runner’s metabolic system. The work is varied, combined, and sequenced over a season in a way that is specific to the energy demands of the 5k race. Workout loads and session sequences designed for the 5k are similar to those of the 3k and 6k, but look far different than what is done for the 800, 1500, and 10k events. We can safely say training is event-specific in the distance events. While volume is stressed in events longer than the 5k, the intensity is stressed in the events shorter than the 5k. Today we well focus on…
