Incorporate a mix of shorter, faster runs and longer, slower runs into your training routine to improve both speed and endurance.

One effective technique for building running endurance is to include brick sessions in your training. Brick sessions involve transitioning directly from a bike ride to a run. This simulates the feeling of running off the bike in a triathlon and helps familiarize your body with the unique demands of the run leg. By practicing brick sessions regularly, you can strengthen your legs and enhance your ability to maintain endurance while transitioning between disciplines.

Training for short and long course triathlons requires different approaches to building endurance in the run leg. For short course events, where the run leg is relatively shorter, focus on maintaining a strong, steady pace and incorporating intervals to improve speed and efficiency. For long-course events, where the run leg can be a half marathon or more, it is crucial to develop functional running strength and pacing strategies. Negative splits, where you run the second half of the race faster than the first, can be particularly effective for maintaining endurance over longer distances.

To summarize, building endurance in the run leg of a triathlon requires a combination of progressive training, brick sessions, and tailored approaches for different race distances. By following these techniques and implementing a smart pacing strategy, you can improve your running endurance and perform your best on race day.
