Race Predictors

It's fun to think about what your latest personal best means you might be able to manage for other distances. This is where race prediction tools can help out.

Our General Race Predictors tool shows the predictions from, and compares, the Riegel, Cameron, Vo₂ and Age Grading Models. While the more-specific Kosmin test calculator works out what you might run for 800m and 1500m based on the results of a timed test.
