TCKRA Martindale Triathlon

48th Annual Martindale Triathlon October 31, 2026

The Martindale Tri is reputed to be the oldest triathlon in Texas. It is brought to you by the Texas Canoe and Kayak Racing Association.  It is unique in that the swim leg has been replaced by a paddle leg (canoe, kayak, or SUP) down the beautiful San Marcos River. 

The Tri kicks off with a 7-mile run through the quaint little town of Martindale, TX.  Next up is the bike, which covers 22 miles (on a paved road) just outside of Martindale and Staples. Finally, a 5.5 mile paddle from Shady Grove Campground (aka Spencer Canoes) down to the 1977 bridge in Staples.
