Event details

Donner Lake Triathlon begins in clear alpine water before sending athletes onto mountain roads and shoreline running routes, with several distances across two days widening the field and keeping West End Beach active all weekend long each July. West End Beach’s shallow entry makes the swim start easy to watch from just a few steps off the sand.

The beach-based start and finish make this an easy triathlon for families to watch without chasing a course across town, since both transitions happen at the same shoreline location, leaving plenty of time for lake play between race distances.

Altitude, packet pickup, and early starts make Truckee-area lodging valuable for competitors and their families alike. Reserve a Stay well in advance, pack layers for cool alpine mornings, and use an extra day for paddling, hiking, or a scenic drive over historic Donner Pass. It is a well-organized, family-watchable triathlon set against genuinely striking mountain scenery, with two full days to see different distances race. Morning water and air temperatures both run cool at this elevation, so pack real layers for the early hours.
