I kind of get the doping thing, particularly among masters racers.
Several years ago, I suffered a pretty severe injury. It took me out of racing and training for a full year. By the time I could start training again, it was like starting over. I was struggling for awhile, and it was depressing. At one point, I thought, "Man, if I could just take something to get back to where I was, that would be so nice." And when I thought that, I realized there was something I could take. I could dope.
I opted against that.
But other people don't. There was a local guy who got popped for doping. He had multiple rainbow stripes. He basically admitted that he started doing it because he wasn't keeping up anymore, and he didn't like losing.
