Course Description

Each distance of the Kerrville Tri will begin with a swim in scenic and calm waters of Nimitz Lake formed by the dammed Guadalupe River that flows through town. The course is marked with safety features including sighting buoys and lifeguards. Just a short distance from the swim exit is the transition for the bike course,T1. T1 is located in the grassy field behind the Community First National Bank, on Hwy 16 at the intersection of Guadalupe St.

The famous bike course leaves T1 for a ride through the historic downtown district. For 2021, we’re working with the City of Kerrville and TxDOT on adding a dedicated lane for cyclists on Highway 27 between Happiness Road and FM 1350 due to TxDOT adding rumble strips on the shoulder. This affects the Quarter and Half distances on Sunday.⁠

From here the Half and Quarter Distance will continue out of town for a fast ride through rolling ranch country side and by creek fed water crossings. The Quarter Distance will do one loop and the Half Distance will do two full loops. For the second loop, instead of turning onto Park Lane, bikes will continue down La Casa to the second transition area (T2) located at Louise Hayes Park.

Starting in 2015, the Kerrville Triathlon Run course is held entirely on the paved Kerrville River Trail. This scenic trail follows the Guadalupe River from Louise Hayes Park all the way to Kerrville Schriener Park. The Half Distance will complete two 6.55 loops, while the Quarter and Rookie Distances run courses will be a single loop.


All events at the Kerrville Triathlon Festival will use a two transition area format. T1 (swim to bike) and T2 (bike to run) are in different locations approximately 2 miles apart. Participants will ride their bicycles during the event from T1 after the swim to T2, where they will begin the run.
