Entry Fee Includes

Fun and challenging course design, limited race entry of 300-450 athletes depending on park, professional race operations, wonderful volunteer support, aid stations stocked with water and Gatorade, medical support, chip timing, accurate results, timely posting of results at the event and on the EX2 website, plentiful post-race food (breakfast burritos and other tasty treats - yum!), electric atmosphere, great music, awards, and colorful t-shirts (one/person for the series. see below).


High-quality Zorrel t-shirts for men and Next Level t-shirts for women are distributed at these races. The Zorrel Z100 men’s tees have a cotton feel and microfiber Dri-Balance Lifestyle Moisture Transport Technology. The Next Level ‘boyfriend’ women’s tees are a 100% super soft combed 4.3 oz cotton jersey with a slim fashion fit, a longer length, and longer sleeves, like your boyfriend's old t-shirt but with a fit for women. Any racer may order either the men’s tee or the women’s tee. All racers that register at least 10 days before the event are guaranteed a t-shirt in their specified size. In an attempt to predict racer participation, we will order some additional t-shirts. However, those registering within 10 days of the event will receive t-shirts while supplies last. Racers will receive one t-shirt for the entire series, regardless how many races in the series are entered. The vast majority of racers do not want more than one t-shirt and this policy enables us to keep the reg fee as low as possible.

Hi-Res Race Photos

As the official photographers of EX2 Adventures, Swim Bike Run Photo captures the spirit of adventure and friendly competition at each of our races. They offer digital downloads and traditional prints. The very talented photographers at SBR take thousands of photos at each race and they all go online within 14 days of the event. A link to their website will be available from the ‘results’ webpage. If you see a photo you fall in love with, please support this awesome company and make the purchase.
