Texas' Premiere Triathlon Race Series.

For about a decade, Bayou City Triathlons has lead the way in multi-sport race production throughout Houston, Texas. The Cypress, Towne Lake and Kemah Triathlons are unified under the Bayou City Triathlon Series (BCTS) umbrella. The BCTS registered over 6,500 athletes last year with over 1,000 of them coming from the youth triathlons associated with the adult events. From beginners to elites, athletes of all levels are encouraged to participate at our events. 

We have your investment covered!

New Event Insurance!

In order to provide the best race experience possible and protect your financial investment in your registration fees, we've upgraded our registration platform and added race cancellation insurance!  For you, this means in the case of a race being forced to cancel do to certain circumstances out of our control, such as severe weather, you will receive a full refund, at no extra charge to you.


Further, you can add on a low-priced personal insurance option in case life happens and you end up not being able to make it to the event at the last minute! Sorry, no more excuses for not registering - go get to training!
