No worries, Bill Clinton used to be referred to as "Bubba" and he's a Rhodes scholar! Bicycle racing is like most competitive events - it is inherently dangerous especially considering speed, hard pave and thin lycra. Luckily standards for head protection are much better now, a bicycle helmet has saved my scalp a number of times over the years riding, training and racing. Had a couple concussions, broken collar-bone, cracked ribs, stitches and plenty of 'road-rash'. It's part of the deal if you are a serious advocate of two wheels. (ask Gaolee) The Tour de France can be a bit confusing to a novice but it can be broken down enough to enjoy watching. A lot easier to understand than Cricket! I bet there's short on-line tutorials on how to understand how it all works. For local amateur races - a criterium (less than a mile circuit around-and-around for multiple laps with left and right hand turns - usually flat) is exciting to watch and you can walk the whole course to get different perspectives. They can be held in city squares or industrial parks. Any time I attend one these days my juices start flowing! (I don't race anymore)
Track racing (which I also did) is a very specific arm of racing bicycles. Not all roadies do track, and some track racers only race the track. A whole 'nother kind of adrenaline-fueled excitement - 1 gear, no brakes (except by back-pedaling on the "fixed" gear), really tight proximity, very fast split-second moves and lots of aggression. Needless to say - not for everyone, even for a lot of experienced road racers.
