The 7 mile run is the first event of the Martindale Triathlon. The starting line is on 1979 at the entrance to Spencers Canoe and Shady Grove campground.
Over the years, the 16.5 mile bike loop course starting and finishing at Spencers Canoe and Shady Grove CampGround has gone through the least amount of changes as compared to the run and paddle courses.
The 5.5 mile canoe/kayak paddle follows the cycling segment and is the final event. The start of the paddle is at Spencers Canoe and Shady Grove Campground in Martindale and follows the San Marcos River to the Staples Bridge.
