This is my first post, so if I'm in the wrong area, please be forgiving.
I'm planning on doing this year's Ride to Conquer Cancer http://www.ridetovictory.org in the Louisville/Lexington, Kentucky area. This will be my first long-distance ride; as it's a little over 140 miles over September 25-26. I'm 25 and in good shape and have begun riding about 20 miles a day for the last week or so. However, I'm pretty sore when I get off, not because of the fatigue, but from sitting on the seat and the angle at which I lean on the bike. Also, I've included a picture of said bicycle on the post. It's pretty old but, due to a lack of funds, it's what I have for the time being, and what I'll probably be riding during the event.
I'd really appreciate any suggestions anyone can offer as to things I should change, replace, have looked at, remove, etc from the bike. I'm working hard to raise the money required ($2500) to participate in the event and I would hate to have something happen to myself or the bike while on the road, after all this work.
Sorry for being so wordy. And thanks everyone!
