Speed & Distance Calculators

Whether you are measuring your progress on a familiar training loop or estimating a finishing time for a time trial, accurate speed and distance calculations are fundamental to cycling. The UK uses a mix of miles and kilometres depending on context — road signs show miles, but most cycling computers and events like British Cycling time trials report in kilometres. Our speed calculator and distance calculator handle both units, so you can work in whichever system you prefer and convert between them effortlessly.

For competitive riders, the time trial calculator estimates finish times based on your power output and course profile, which is invaluable for setting realistic targets at local club 10-mile and 25-mile events. The split calculator helps you plan even pacing — the most efficient strategy for time trialling on the flat courses found across the Fens, Essex, and the Welsh borders. The average speed calculator is useful for analysing rides with multiple segments, giving you a true picture of your performance rather than a single misleading number.

The cadence to speed calculator bridges the gap between your pedalling rate and your road speed, showing how different gear choices affect your velocity at any given cadence. This is particularly helpful when dialling in your gear selection for specific courses. For riders who use GPS, the GPS distance calculator applies elevation correction to give a more accurate distance figure than raw satellite data — accounting for the constant undulations that characterise most British roads.
