Thanks for the confidence boost guys, really appreciate it. It looks like I'm going to sign up tomorrow afternoon. I sent an email to the coordinator and she said the course isn't that hard and that new riders shouldn't be worried about it. I don't currently own any cycling shorts but I've read that it gets painful when wearing regular shorts for extended distances, so I'll buy some after work!
I know this isn't the proper forum, but can I get some tips on food and carrying it? Right now I plan on carrying nothing besides a tube and repair kit (patch and such). I've only changed a flat once and it took me forever, so hopefully if I get one another cyclist can help me

. Should I just bring a few oatmeal bars for food or something? I don't want to take extra bags besides what I can fit in the under-seat bag.
I also have two water bottles which I guess will get refilled at the rest station.
