Texas' Premiere Triathlon Race Series.
For nearly a decade Onurmark Productions has lead the way in multi-sport race production throughout Houston, Texas. The Kemah, Cypress, and Towne Lake Triathlons are now one entity, all 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.
