The example athlete below is preparing for a a flat ironman race at the intermediate level. We presented him with three power based plan options to demonstrate the costs associated with riding harder vs running faster.

To further prove the point, below for each athlete ability we have charted the faster, at goal or slower time predicted marathon based on how hard you ride your next ironman race. Note that we are giving estimates for long course triathlon however the same concepts hold true for half ironman and olympic distance racing.

Minutes faster (-) or slower (+) for and Ironman marathon based on how you bike

Marathon split slower or faster by minutes based on IF of bike split
