Runners (doesn't matter what sex but men are usually the worst) wearing really expensive gear (Yeah, I see those $250 shoes and that $150 Under-Armour top and those $150 Nike running tights, bub!):
You can't be bothered to help the lost cyclist AT ALL.
You stopped to ask if I needed help. Not just one of you. Four well-dressed, well-equipped cyclists stopped to inquire if I needed help. The best equipped guy, who's probably getting ready for some Pro-Am thing was so damn nice, I was almost in tears.
I could have been dying in a ditch and the runners would have jumped over me, yelling at me because my blood is making the road slippery.
Runners are (for the most part) stuck up. Sorry, but all those rabbits out there, running their brains out getting ready for whatever race they're in (Akron, Columbus, The Towpath) are a bunch of snobs. I've been in races with ya'all and you're a bunch of self-centered buffaloes.
Maybe it's because a bike can break down? Maybe it's because some cyclists ride in groups or on teams? Maybe because a Tour De France winner from 1954 can still get on a bike and tootle around at 80 years old?
I don't know. I like being in foot events (medals, t-shirts, goodie bags, "health" expos, shopping, Oh, MY!) but for the most part, the other participants (unless there's a walking division) are NOT nice people.
