All proceeds will benefit the Greater San Marcos Rotary Foundation (501c3).

The Rotary Club of Greater San Marcos is proud to offer a sprint triathlon at the renowned Springs Lake (formerly Aquarena Springs). "The prestigious Spring Lake is located in a 250-acre preserve. About half of the property is in the Edwards Aquifer Recharge Zone, and all of the property is part of the Sink Creek watershed." (

With such a precious protected lake, the lake is closed to the public to swim in 363 days out of the year. Only two times during the course of a year is the crystal clear lake opened for public swim. The Rotary Club of Greater San Marcos event, Spring Lake Triathlon, is one of those times. It is indeed a privilege to swim in the lake!

The Springs Lake TRI has limited slots available. It's important to register NOW to ensure your participation. As a participant, you will receive a registration packet, which includes a t-shirt, promotional materials from sponsors, a free coupon booklet to the famous outlet malls, and you will be able to take part in the post-event food and entertainment.  This would be a GREAT time for you to mingle with fellow participants.  Additionally, awards will be given to each division.
