Not me, I like it when I look behind and see a group of racers coming up on me at the beginning of my ride, when I'm fresh. I put on the power and keep them at a distance, often it gets faster and faster so I know they've taken the bait. They just have to catch this big guy on his hybrid. I always try turn to turn off up a side street before I reach my limit though, sometimes I win, sometimes the racers catch me first but I aways give them a good run for their money. lol.
