AQUABIKE

The Aquabike Races is an endurance sport composed of swimming and cycling stages. It’s an ideal race for athletes who are focused on the swim and bike legs of the triathlon without the run.

Did you know Waco is the home of the first triathlon ever held in the state of Texas? The Waco Striders hosted the first triathlon in May 1980 with 24 men and one woman competing in the Olympic distance at Lake Waco with the staging area at Speegleville Park.

The event grew to 500 entries with a waiting list each year, with many triathletes considering the Waco Triathlon the best in Texas. The last Waco Triathlon was held in 1991 and was reimagined as what is now TriWaco in 2009.

We are confident that TriWaco will continue to grow in popularity year after year and continue to be one of the most challenging and fun triathlons in the state.
