I think they should have more divisions that aren't based solely upon your age and what not... but by your physical aspects, like fattness, height and that kind of stuff...it sounds cooler...
Events divided into body aspect categories would destroy competition.
The best thing about running is that you compete against everyone! If you're the best (fastest & best endurance), you will win. If others want to beat you, they just have to train hard and most of the time they'll never get there due to genetic inadequacies and barriers.
Now, get training :p
On another note:
I've heard Buffmeister previously discussing weight graded times i.e. times adjusted to weight - it would be interesting to see what that would do for race results. Probably need to make adjustments based on height and weight.
