RT66 Multisport Festival


This historic race is as traditional as they come, the festivus features: an Aquathlon on Thursday, Olympic and Sprint distance triathlons and duathlons and an Olympic distance Aquathlon on Saturday. 

Join us on Thursday night for a short splash n' dash. This is an excellent way to get a practice swim in the lake before the races on Saturday. 

The water in Lake El Reno is usually wetsuit legal, so be sure to bring a wetsuit if you want to. Water temps will be measured before the race and wetsuit legality will be called on race morning.

The Sprint Triathlon will include a special high school division, with entry at a special discounted rate. High school athletes must be of high school age and be able to prove that they are currently enrolled in high school or a home school equivalent. 

The Olympic Tri, Sprint Tri and High School Tri are all State Championship races that may qualify participants to enter the USAT age group Nationals.
