The Boulder Stroke & Stride is a Swim/Run event, also known as Aquathlon. The race begins with an open water swim of 750 or 1,500 meters. There will be a mass start for each distance, with 1,500 meter swimmers starting at 6:00pm, and the 750 meter swimmers starting 5 minutes later. On evenings with an exceptionally large crowd, we may go to a 4-wave start procedure.

The swim course is a rectangular shape, with participants swimming in a clockwise direction around a series of large orange buoys. One lap of the swim course is 750 meters. 750 Meter swimmers swim one-lap of the course, then exit the water and run 50 meters to transition. 1,500 meter swimmers also exit the water following their first lap, then run 100 meters along the beach, and start lap-2 at the same point where they started lap-1. Upon completion of the second lap, 1,500 meter swimmers will run to transition.

The transition area ia a large grassy area were you will lay your towel. This claims your transition spot. You will place your running shoes and other gear on your towel. Upon completion of your swim, you will run to your towel, pull on your running shoes, your bib number, and any other gear you'd like for the run. You will leave your wetsuit, goggles, and swim cap at your towel. Once you are ready, you will exit the transtion area, and start the run being careful to exit at the correct location and cross the timing mat to record your run start time.

The run course is an out and back course on a mix of paved and dirt roadways. The first and last half-mile of the run is open to light park traffic. You will run on the right side of the road in both directions. All miles are marked, and there is a water-stop at the turn-around. The run course has one small uphill on the way out, and one small downhill on the way back. The rest of the course is flat.

Following the run, we'll collect your timing chip, and if you are one of the lucky finishers who was chosen for a raffle prize, you will receive some merchandise or a gift certificate from one of our generous sponsors! Food, drink, and music follow the event.
