Course and Maps

The Annual TriWaco Triathlon features both Sprint and Olympic Tri courses, which begin with an open-water swim in the Brazos River transitioning to a fast & flat bike course and ending with a beautiful run along the Brazos.


Due to extensive construction on the area highways and on the suspension bridge, TriWaco will have some course adjustments for 2021.

All maps will be updated as soon as possible.

Sprint: Starting almost directly below the Historic Suspension Bridge, swimmers will start in age group waves for a 400-meter rectangular swim in Lake Brazos. Despite being an open-water swim, the course will be very beginner-friendly with the swimmers never being more than 50 meters from land. City of Waco lifeguards will be posted on shore and on boats. The swimmers will cross beneath the Suspension Bridge before exiting, which will make the bridge an excellent viewing platform for spectators.

Olympic: The starting and ending point will be the same as the Sprint, but the distance will be a more challenging 1500 meters. The Olympic swimmers will pass underneath three additional bridges and spectators will have access to the concrete river-walk for the entire distance.


Water temperature is typically ~86 degrees in the Brazos River in July. It is suggested to plan that wetsuits will not be allowed in the race. Water temperature will be posted at expo and official water temperature will be taken race morning. TriWaco uses USAT wetsuit rules, see below.

USAT Wetsuit rules:

Each age group participant shall be permitted to wear a wetsuit without penalty in any event sanctioned by USA Triathlon up to and including a water temperature of 78 degrees Fahrenheit. When the water temperature is greater than 78 degrees, but less than 84 degrees Fahrenheit, age group participants may wear a wetsuit at their own discretion, provided however that participants who wear a wet suit within this temperature range shall not be eligible for prizes or awards. Age group participants shall not wear wet suits in water temperatures equal to or greater than 84 degrees Fahrenheit.


After leaving the transition area the riders will leave downtown and quickly find themselves riding by the new McLane Stadium and Baylor University. The ride is moderately flat and very fast. SAG support will be provided for minor mechanical problems. The Olympic distance is 40K and the Sprint distance is 20K. There are no aid stations on the bike course.


Sprint: The runners will be on a wide concrete trail that runs along the river into Cameron Park and is mostly shaded. The 5K run will be flat except for the ramp that leads up to the Herring Street Bridge. After the protected bridge crossing, the runners will run on a concrete river trail before crossing Lake Brazos for the last time to finish on the Historic Waco Suspension Bridge. The route will have clearly visible distance markers and a water station at the halfway point.

Olympic: The Olympians will get an additional 5K in Cameron Park by running on the pavement to the turn-around point. This is some of the most beautiful running in Texas and will include about 250 feet of total up-hill climb!  The Olympic route will rejoin the Sprint route at the ramp for the Herring Street Bridge. There will be four aid stations on the run course stocked with Powerade and water.
