Ironman Lake Tahoe courses will cover the North Tahoe and Truckee region with the start of Ironman at 6:25 a.m. in Kings Beach with the 2.4-mile swim in Lake Tahoe. The 112-mile bike course will make two loops through the North Shore and Truckee before finishing at Squaw Valley. The race concludes with a 26.2-mile run along the Truckee River from Squaw Valley to Tahoe City and back.
There will be a Practice Swim at Kings Beach State Recreation Area on Sept. 20 from 7 to 9 a.m. and everyone is welcome to watch.
There will be road closures and delays throughout the day along Highway 28 in Kings Beach, Highway 89 north, the historic downtown in Truckee, in the Schaffer Mill area, Northstar and on Highway 267 between Northstar and Kings Beach. See the list of road closures and detours for details.
The swim starts off the race with two counter-clockwise loops with the Pro Start at 6:30 a.m. and the Rolling Age Group Start at 6:40 a.m. The swim will start on Kings Beach State Recreation Area on the west side of the pier and then each loop will finish on the east side of the pier. There will be a short beach run between the two loops.
