How do I train for my first cycling event?
I have never ridden with a cycling group but I really want to participate in a cycling event in my area. It's in September and they are offering a 25, 50, 75 or 100 mile ride. I can ride 21 miles with no problem on my own. My question is since I've never ridden in a group should I just do the 25 mile instead of shooting for higher? Also, how would I train or prepare myself for something like this. I'm a bit intimadated to ride in an event where there is going to be a lot of people.
Any advice for someone who'd like to get into riding charity events etc?
