ACWR for runners: Which injuries it can (and can’t!) predict
Somewhere in the last fifty years, running acquired a rule: “Don’t increase your weekly mileage by more than 10 %”. The 10 % rule gets mentioned all the time, but nobody is quite sure where it came from. It’s a rule of thumb, a nice and easy thing to remember, it sounds sensible and it’s easy to calculate. But the 10 % rule has 0 % scientific evidence going for it, quite worse in fact: almost 20 years ago a randomised control trial concluded that the 10 % rule makes no difference whatsoever to prevent running injuries (Buist et al. 2008).
