The fastest road races

Flat courses are fast courses. We rank the races in RaceDayCast by what the course costs you in time – every climb and descent, worked out by our pace model (going down gives back less than going up costs). Switch on the typical race-day weather to see how heat and wind change the picture.

The time is what the course (and the weather) adds to – or takes from – a finish of 3:30 in neutral conditions on a flat course, in a normal race field. Faster runners lose a little less in seconds, slower runners a little more. Typical weather is the last 10 years around the race date (NASA POWER): heat from the average race day at the start time, and wind at the typical wind speed, averaged over every direction – on the day it can be very different. ≈ = elevation from the GPX file, not a terrain model, so the number is less certain. Course records and winners are added by us from the official results. Updated 25 October 2026.
