Ratings Guide

Ratings reflect the impact on pace. For example: altitude generally has a lower impact on your pace than the terrain. These factors are reflected appropriately in the overall rating. Our proprietary algorithm considers a number of immutable course measurements, such as race date, climate, location, elevation gain, and distance. These measurements are used to anticipate an objective and unbiased difficulty assessment - the Course eXperience (cX)™️. Please note: we receive race information from a number of sources, such as public user submissions, and we cannot always verify the submissions. To ensure neutrality, race-day weather changes are not considered. the cX rating allows runners to easily predict and compare races.
