Training Pace Calculator

Train too hard, and you'll probably burn out or get injured. Train too gently and you simply won't make the most of your potential (but hey, that's okay). This calculator uses one of your recent race times to reveal how fast you should run the different components of a training week.

Race-time Predictor

Racing isn't a mystical science. If you know how fast you've run at one distance, a little empirically-based algebra can give you a pretty good idea of how swiftly you might run at another. This calculator does exactly that.

Race-pace band

A tool for race-day. Type in your target time, then print out and wear this band. It shows the mile or kilometre splits you'll need to hit along the way. Useful for all distances, particularly the marathon.

Calorie Calculator

Type in your weight and the distance you covered on your last run to discover just how many calories you burnt over the course of the session.

BMI
