The race

Arguably the fastest full-distance course in the world: downstream swim, flat bike and flat run.

Course

SwimRiver

Downstream point-to-point swim in the Sacramento River with a helpful current.

Bike100 m (328 ft) elev.

Completely flat, wide, closed-road loops through the Sacramento valley farmland — extremely fast if the wind stays down.

Run30 m (98 ft) elev.

Flat run on the American River Parkway bike paths and along the downtown waterfront.
