Don't know if anyone else has seen the story on the front page of today's Telegraph online, but "experts" (ahem) are now saying that we should only run for between 30 and 50 minutes at a time and do no more than 1 or" a few" marathons or triathlons in our lives. Otherwise, we risk an early death from heart failure. This appears to be based on nothing more than the realtively early death of Micah True from "running too much", although Pheidippedes also gets a mention.
Appreciate that this sort of story comes round fairly regularly and will no doubt be seized upon by couch potatoes everywhere (some of the readers comments underneath the story are so typical). I doubt if it will make the slighhtest bit of difference to any of us, but the danger is it might put off some people from taking up running in the first place.
