How rough the surface is. Based on what you're actually riding on — smooth road, gravel, technical off-road, or snow. If a race mixes surfaces, we score it by the toughest one present, not an average.

How hot conditions are likely to be. Based on where the race is and what time of year it runs — a race near the equator will always run warmer than one near the Arctic Circle, even in each region's own hottest month.

A single big-picture tier combining total distance and total climbing, so you get one quick read on how the race stacks up overall.
