The races are rated from 0 to 6 to indicate the difficulty of their course, considering factors such as distance and elevation. In the runner's profile, they reflect the experience gained by the runner in race of a certain level of difficulty.
Race Score Explained
Each completed race is given a "Race Score". This score represents a runner's performance level in a race, on a scale from 0 to 1,000 (1,000 being the best possible score).
The calculation of each score is done using an algorithm that takes into account all factors that have a direct influence on the runners' performance: distance, elevation gain, altitude, race conditions, technical difficulty, and the runner's time. For each race, the score varies based on these data.
