I'm going to be walking a 5K on a track in the near future and they said it's about 13 laps around the track we are using...
PROBLEM...how on earth am I supposed to be able to keep track of how many laps I have done?
I thought about using my little clicker that I use to count rows when knitting but I don't want to have to hold it in my hand and I think it might get sweaty in my pocket. Any ideas? Also, I don't want to spend $30 on a lap counter just to use once.
