How far should I run for sprint intervals?

Hi Jared. Like other types of exercise, your sprint training should be used to mirror the purpose for which you are doing this type of training. I’m going to assume that you’re doing this type of workout to prepare for a certain sport or physical activity, so taking a look at your typical ‘work-to-rest ratio’ for your sport will help you to answer your own question. Unless your sport incorporates fairly consistent sprints of a certain distance (say 40 yards), then I would conduct my sprint intervals for TIME instead of distance. By doing that, this would allow you to calibrate the duration of your work (i.e. sprint) and then the duration of your rest before running your next sprint. To my mind, this would be a more effective way to do your sprint or anaerobic training if your intention is to prepare for competition.

I hope that this helps.
