For those that have been around you know Sylvan Beach is a legendary Houston area triathlon and duathlon. As of 2019, the Sylvan Beach Triathlon is now under the Bayou City Tri Series banner. We are keeping everything the same for the most part. But we are excited to announce the addition of the Olympic distance Tri and also we are moving the finish line arch to the edge of the ocean. So you finish through the sand, and straight into the water. We’ll be waiting for you with the best beach party your tri suit has ever seen! To register visit

Refund Policy
We have a very strict no refunds, transfers, or deferrals policy. Much of what goes into producing an event like this is spent up front and offering refunds, transfers, or deferrals may effect the future of the event because funding is allocated early. Please do not signup unless you are sure you'll race and/or you're willing to accept the registration loss if you end up not racing, for whatever reason. Thank you.

It is your job to frequent the website and check your emails. If you use a work email there is a good chance our emails and website will be blocked by your firewall. Use a personal email address and check the site from home. Like us on Facebook and join our newsletter to get the latest information.

Any changes made to the race are done because we have to, out of safety for our participants. These issues, when they do occur, arise after the race has been planned. We are triathletes too and do everything to create a better, safer, more enjoyable experience for all of you.

USA Triathlon Membership
A USA Triathlon (USAT) membership is required. You will be able to purchase a one day or one year membership during registration.
