What distance are you training for?

This is the new distance you haven't raced before — or want to run better. We'll predict a realistic goal time and the training paces to get you there.

How would you describe your running experience?

This adjusts the prediction formula. Experienced runners maintain pace better over longer distances — beginners slow down more in the final miles.
