Course Description
Swim: Accurate course in beautiful Stoney Lake, water will be 20-22degrees. Wetsuits are encouraged but not mandatory. Small 300m loop or 750m loop. Deep water start, boat ramp exit. Wetsuits for sale & Rent at Runner's Life
Bike: Out and back 5k or 10k on Birchview Road. One of the most scenic roads in all the Kawarthas. Some rolling hills, a beautiful tree canopy and some fun turns. Open to traffic (it's a quiet road) so keep to the right of the road. OPP control the only stop sign on the course so you have right-of-way. Beautiful pavement for the bike course but 400m of gravel to start/finish the course, don't worry, if you have a fancy TT bike it'll handle the light gravel without problem.
Run: Out and back 1.5k or 2.5k on Golf Course Road. A quiet country road with rolling hills and a bit of tree cover but not much. Water station at 1.5k/3k
Accurate course & chip timed.
