I'm participating in my first charity ride this coming weekend. But, because I'm riding with a friend I opted to do just the 10 mile ride and I've not ridden in a group ride on my road bike before so I thought the 10 mile option would be a good starting point. So, question is do I go ahead and ride my road bike that I'll be clipped into or do I ride just my hybrid bike that I can wear normal shoes on? OR, should I possibly put normal pedals on my road bike and go ahead and ride that since this is a somewhat hilly 10 miles. I'm still undecided on which bike to ride for this, and because I've never ridden in a group I'm not quite sure how comfortable I'll feel being clipped in.

Any advice would be appreciated.
