Horsetooth Reservoir and Lory State Park are ideal locations for a swimrun event due to their scenic and varied landscapes. The event offers a combination of open-water swimming in the reservoir and trail running through Lory State Park’s diverse trails, which cater to different skill levels and provide breathtaking views. The proximity of these two venues allows for a seamless transition between swimming and running, making it an exciting and challenging experience for participants and providing event organizers with access to amenities and support infrastructure. Ease into race mode with a pre-race shakeout in the Swimming Area at Horsetooth Reservoir. Spend your post-race recovery in the sauna and cold plunge at the finish line.
