Just had a great question from an athlete. “When should I replace my running shoes?”
We can complicate this with many different versions of course but the centre of the envelope answer is around 800km. The variances to this rule would be the amount of trail running you do, how heavy you are, what type of shoe they are etc.
When we had our running night with Ryan Quintano at the run shoe shop he said one of the best things you can do for injury prevention is also to have 2 pairs that you rotate.
