Talking to the ultra-runner at work the other day, he said he had 6 pairs of trainers for his running. At first, I couldn't believe it but then he broke them down: -
2 pairs of every training shoes (alternates)
1 pair of cross country
1 pair of sprint
2 pairs of marathon trainers.
So it's kinda understandable but it got me thinking - why would anyone train in one pair of trainers and then have a different pair for races? Is there a particular reason for that?
