About RaceIndex™
RaceIndex measures the difficulty of endurance events on a 1-to-100 scale based on the course's terrain and environmental conditions including elevation, elevation gain, temperature, humidity, wind, and water conditions.
The index uses average historical weather conditions for each race's ranking and begins to use forecasted weather data for events less than 14 days away.
