Guelph Lake I Triathlon and Duathlon
The event takes place June 20 and 21, 2026 at Guelph Lake Conservation Area as part of the Subaru Triathlon Series. Multiple formats are offered, including triathlon, duathlon and relay options. The sprint triathlon and sprint duathlon include qualifying spots for the 2026 World Championships.
Swim starts use the beach and a clockwise rectangular loop marked by large orange buoys; water temperatures are usually comfortable. Bike courses are out-and-back on open, exposed roads with rolling hills; competitors should be aware of speed bumps on the road in and out of the conservation area. Run courses stay inside the park on paved roads with short rolling hills.
Race kits are distributed on site behind the snack bar, down the hill from transition. Race day registration is available for a $5 late fee; accepted payments include Visa, Mastercard, debit and cash. Participating athletes are included in entry; spectators pay park entrance fees.
Relay teams share a single timing chip that acts as the exchange device; the swimmer begins with the chip on the ankle. Relay teams have a dedicated area in transition and athletes must pick up kits together and sign waivers. Visit the organization's website for the most recent information.
