​Training Opportunities
Looking for ways to train for the SLO Triathlon? Avila Bay Athletic Club will be launching a Triathlon Clinic on May 26 just for us! See flyer for more information.

The 2015 SLO Triathlon is on Sunday, July 26. Over 300 volunteers are needed to create a successful event for the 1200 participants. Volunteers are stationed from beginning to end along the course to provide a variety of services during the event. Volunteers may be asked to perform the following tasks: count laps at the pool, monitor barricades for vehicle traffic, direct participant traffic on race course and cheer on the participants. A City of San Luis Obispo volunteer waiver may be prepared in advance of volunteer check-in. Please complete the Volunteer Form and Waiver if you are interested in volunteering your time for this outstanding event! Waiver can be dropped off at 1341 Nipomo Street in San Luis Obispo or emailed to Brian Roberts at
