Running Calculator

And how can you stick to a pace on race day?Look no further than these interactive calculators for help...

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
Calculate your BMI to determine if you're in a healthy weight range.

Heart Rate Zones
We can help to discover your heart rate zones based on Tanaka formula.
