Donner Lake Triathlon Information
2027 brings the 45th Donner Lake Triathlon (DLT) to Truckee, California. For years, the DLT has been, and remains, a favorite triathlon for many. It’s no wonder, as the event features an epic setting, a beautiful and challenging course, and a location near Truckee and North Lake Tahoe. 2027 also marks the 15th Donner Lake Kids Triathlon and the 13th Donner Lake Half Triathlon. We welcome you to Truckee and North Lake Tahoe. Be sure to stay before or after to experience one of the World’s best sporting playgrounds.
Big Blue Adventure owns and operates the DLT. Big Blue Adventure produces many sporting and endurance events, including the Lake Tahoe Triathlon, Truckee Half Marathon, Tahoe Trail Running Series, XTERRA Lake Tahoe, and other Epic Truckee Tahoe events.
