Mixing Up the Systems

It’s important to train all of our metabolic systems within our training. This is why we do the long ride, the track sessions and the short rest intervals in the pool. Mixing up these systems within a training session is a way to make even larger gains, especially for the sprint and Olympic-distance triathlete. In these races, everything happens quicker and the time gap to make a move or react to others is much smaller and can be much costlier. This means that being able to switch between the different metabolic systems quickly and becoming very efficient at utilizing energy from each system without long transition gaps is crucial.

Below are sample workouts from each discipline that will train your metabolic systems to transition quicker. Do these workouts and you will be better prepared for your next sprint or Olympic-distance race.
