I'd be interested in doing the donut eventually, but at this point just going 70km at any speed is probably going to be a bit of a challenge. How hilly is the route?
You'll be happy to know it's constant uphill to Keele. Then about 10-15kms up on Keele it goes to be a roller coaster ride with effective positive elevation gain all the way till it turns around.
Up down up down up down up down. Come out on sunday then we have 3...!! I'll probably get dropped around elgin mills which is great, cause then i can head home
I'll wait for the group at Steeles/Yonge but if I do that then i've missed most of the tempo ride.
Edit: Anyone reading this update me on the weather situation where you are. I'm looking at the radar imagery and it looks like the **** is about to hit the fan.
