Just moved from Halifax, NS, to St. Catharines, Ont. I find that it is a fair bit warmer here nad I was wondering what sort of extra messures should I take so that I don't bonk during a ride (mountain or road). I usually carry my camel back that holds two liters of wate, and I think that I should start carrying an extra water bottle with a sports drink in it.

Is one bottle of sports drink enough for a 3 hour ride with the water I carry. What other things can I do to remain hydrated and such.

I've been trying to ride in the evenings for the few hours before it gets dark, but on weekends I'd like to do longer rides during the days.
