Gravel Worlds Triathlon & Duathlon : Branched Oak Lake, Nebraska

The Gravel Worlds Triathlon & Duathlon is a USA Triathlon-sanctioned event held at Branched Oak State Recreation Area near Lincoln, Nebraska on Friday, August 21, 2026. The event serves as the 2026 USA Triathlon Gravel National Championships for both triathlon and duathlon and uses chip timing.

Racing options include traditional swim-bike-run triathlons, run-bike-run duathlons, and a multiday challenge called The Triple that spans three consecutive days: swim, gravel bike, and gravel run. The bike course is draft-legal, allowing riders to form groups during the bike leg.
