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.

cX Points™️

Participating races can score and rank runners based on cX Points. Scoring is based entirely on the runner's pace along with the course difficulty (finish position has no impact). Runners add points awarded from each race finish (the more points the better). Unified rankings allows diverse competitions. For example: two runners could compete despite each running different races and distances.
