Timed Events

FIXED-TIME RACES — RUN AS FAR AS YOU CAN IN 6, 12, 24, 48, OR 72 HOURS.

Races with a timed format — you run loops on a fixed course for a set duration. Single-day events (6h, 12h, 24h) are listed first, followed by multi-day events (48h, 72h, 6-day and longer). Usually flat, fast circuits. Great for runners chasing distance PBs or who want a social, low-pressure atmosphere.
