Western States 100 qualifying races

Every race that qualifies a runner for the Western States 100 lottery, as published by WSER. Unlike some lotteries, this list is exhaustive: a finish at an event that isn't on it cannot be used to qualify.

These are the only races that count

Western States sets its qualifying standard by naming the races themselves: an event that is not on this list cannot be used as a qualifier, and virtual events never count. A finish also has to land inside the qualifying window and beat the time limit shown for that race. WSER reserves the right to determine all qualifiers, so treat this as a mirror of their page rather than a substitute for it.

Qualifying window: Monday November 3, 2025 through Sunday November 8, 2026. A finish outside it does not count, however it went.
