Boulder Sunrise COURSES
Sprint 750m (0.47mi) - Olympic 1500m (0.93mi)
This clockwise rectangular course starts and finishes at the swim beach of the Boulder Reservoir. Kayaks, sea doos, boats, and lifeguards will be in the water to support all athletes. If you need a rest, while in the water, waive your arms or simply swim to the nearest kayak. You can hold on to any vessel without penalty as long as there is no forward propulsion. If you need to cut your swim short for any reason, let the water support team member know, and they will bring you in to shore.
Aquabike Athletes: Complete the Olympic swim and Olympic bike. After finishing the bike, continue under the Run Start arch. Run for 0.1mi to the finish line to complete your race.
