Steamboat Lake Triathlon
2022-07-24 | Steamboat Lake State Park, 61105 County Road 129, Clark, CO, 80428, United States
After last summer this event instantly became a personal favorite for our staff, volunteers, and athletes – come find out why! We couldn’t be more excited about this course, this lake, and the overall experience. The swim starts out in the surprisingly warm waters of Steamboat Lake (74 degrees average race temp), then athletes transition to the most scenic bike course you’ll ever find. You’re more likely to see a herd of cattle crossing the road than be passed by a vehicle! After a ride through the rolling country-side athletes will transition to a 3.5 mile run course that’s 50% on road, and 50% on the dirt trails that hug the lakeside. When we tell athletes you’re running through wild flower meadows, we’re not exaggerating.
Pack the camping gear and make a weekend getaway for your all your friends and family! This year we’re also offering a aquabike, and stand-up paddle-board division!
