To piggy back on fishy's comment about road races (I hate the fat people at the start too)...
I hate when little kids run rampant at the start and almost get trampled then their parents give the other runners dirty looks.
I hate people who run in road races.
I hate anyone who rides a bicycle, even if not in a road race.
I hate Lance Armstrong, not as a person, but just in general.
I hate people who work in bicycle shops. They are weird.
I hate seeing guys in shorts with skinny legs running on the road.
I hate those spandex tights and helmets that bicycle riders wear.
I hate when I'm driving my car and I hit someone on a bicycle.
I hate having to slow for people on bicycles, so I don't.
