XTERRA Lake Tahoe is the all time classic off-road triathlon course. Racers start with a 1500 meter swim from a sandy beach in Lake Tahoe, one of the purest and deepest lakes in North America. The bike section tests racers’ climbing and fitness levels. The bike trail starts up tunnel creek, a somewhat sandy gradual climb. Racers pop out from Tunnel Creek onto the area’s epic Flume Trail, which skirts the mountain side overlooking Lake Tahoe. Riders continue on past Marlette Lake and down a rocky and fast Tahoe Rim Trail. The views are breathtaking! Both the Duathlon and the Sprint will complete the 22 mile bike with approximately 4000 feet of climbing. The 10K trail running course is relatively flat, fast and provides a scenic view through tall pines, aspens, and creek crossings.
