The Tri-City Medical Center Carlsbad Marathon weekend of events requires the help of 2,000 enthusiastic and hard working volunteers to make it happen. Volunteers provide key support to the over 10,000 participants as they reach their goal of completing the Tri-City Medical Center Carlsbad Marathon or Half Marathon. No experience is necessary to volunteer and there is a wide variety of fun and exciting job choices available. Volunteers have the opportunity to meet people from around the country and get a behind the scenes view of this major community event. All volunteers receive an official Race Crew T-shirt and the appreciation of thousands of participants who benefit from their support.
