From the Organizer
Join us at Texas' largest crystal clear lagoon in one of the hottest new communities in the Houston area. This LADIES ONLY race will include a Sprint Triathlon and Relay as well as a Duathlon for those just not ready for the water. Your open water swim will be in the crystal clear waters of the Lago Mar Lagoon where your race will end and the fun begins on their white sand, palm tree-lined beaches.
The Sprint Triathlon will consist of a 300 meter swim, an 8-mile bike and a 2 Mile run. The Duathlon will start with a 1 mile run and then the same 8-mile bike and 2 Mile run as the Sprint Tri. All athletes will finish along the beach and be greeted with margaritas and more, and you are welcome to stay and enjoy all the amenities of LagoonFest after. You'll swear you were in the Caribbean and not Houston!
All athletes will receive a custom race bib and tech t-shirt/singlet along with other yet-to-be-determined, Island-appropriate swag. You will also be eligible for age-group awards, and they will be something worth winning for! Your entry also includes admission to the LagoonFest for the day, and already discounted admission available for your friends and family. Come celebrate the ladies in your life at a race full of encouraging women of all skill levels; this race is perfect for first-timers and all triathletes.

About These Sports
This race spans more than one sport — here’s a guide to each, so you can understand what’s involved and decide if it’s the right fit. For course distances, logistics, and race-day specifics, always defer to the race organizer’s event page.
Triathlon
Swim, bike, run — back to back. The sprint distance makes it far more accessible than most people think. Three sports in one race means three movements to train and race day never gets monotonous.
Duathlon
Run, bike, run. The multi-sport format without the swim. Two disciplines, one race — a great bridge between running and triathlon.
