As I start hitting longer distances in my training rides I'm wondering when should I start thinking about taking breaks and bringing food. As of right now I don't bring any food I just bring my 2 23oz water bottles. My last ride was 20 miles and I still felt good the next day but its been raining since then. I have been slowing to about a 8-10mph soft peddle every 5 to 7 miles and taking some water and bringing my HR down a little then back up to 15+mph again. I'm trying to loose weight so I don't want to take in too much food but I don't want to over do it either.
I found a group that has a metric and standard century ride in September and I'm working to at least get to metric ability before then. For that reason I want to know whats best for training.
