Don't worry about it. You're certain to fall 2 or 3 times. At the least you'll get some bruises and nasty scraps, but you'll probably break an arm or a leg. Big deal, so you'll be laid up for several weeks, off the bike, and put on 10-15 pounds. Then you can begin getting in shape all over again. No big deal, you've done it once, you can do it again.
Just sayin'
