How hard every course ran this season, hardest first. Each meet is rated from the runners who also raced somewhere else: how much slower or faster the same runners went there than everywhere else, and a course that hosted several meets is rated on all of them. Pick a time below to see what each course means for a runner at that level. Every 5K on the Runner Rankings is adjusted by these numbers. The two ends and the first 10 courses of the list are free; every course comes with All Access.
