I don’t know if this version of the story is 100% true. If I was reporting the story (hmm), I’d confirm it. But, if I had been the one to report in the first place that a cyclist beat up a driver and sent him to the hospital, I would have also bothered to ask: How did he get the guy out of the car?
There are a lot of running and triathlon and cycling and sports blogs. They are generally upbeat and cheerful. And unrealistic. If you want sunshine and daffodils, this is not that place.
This is the place for all things endurance sports-related. It's always sunny here.
