Is ultra running good for you?
There are a few unknowns about the long term effects. For example, 100 mile races are something that has only really taken place in my lifetime. I will read any future research into the subject with interest.
As somebody who deals with runners and other sportspeople on a daily basis, I know that the injuries that ultra runners get are not nearly as severe as those that are commonplace in football or rugby. Football players and rugby players often get injuries that plague them for years. There are verry few injuries in ultra running, where the victim is not running again within a few months.
