Tonight we did about 80 kms. It was pretty hot out out. When it's this hot you don't really feel it on the bike but what makes you notice, is that you are banging through 2-3 water bottles and hour. We rode from the Brampton Fairgrounds up to the town of Hockley. Very hilly , and we set a good pace up, and rocketed on the way back. No motorpacing back to the parking lot. It was all us. Nearly killed me tonight. I worked a fairly tough day in the heat, so I was pretty wiped when we got on our bikes.
