I discovered todays top tip this week. Monday I set off for my lunchtime run and within 3 minutes it chucked it down on me. I was absolutely soaked, shoes, shorts, socks, shirt, the lot absolutely drenched. Still it meant I sped up for the run. After I chucked all the wet kit into a plastic bag. The next day I opened the bag and whoa, the ponk. Not nice. So did I take it home? No I stuck it back in the bag. After a week of lunchtime runs it was at really, really bad ponk status.
So if your kit gets wet, especially your trainers. Take it home and wash it
