    Hey Bob! I’m an assistant coach for girls cross country. My boss uses your pace calculator all the time. Before I knew about your PC, I was in amazement how coach could put 40 athletes in groups of 5-7 according to specific times……..then I found out about your PC!!! Now I am in the loop and it feels wonderful! Thanks to you, Bob, our athletes will be running more efficiently, which means faster times, which means PR’s, which means EVERYONE will be super excited and THAT makes my day! ROCKSTAR! Thanks again, Bob!

    I actually run myself and love using it for training. I run for Edmonton Harriers and Phil Booth is my coach. My mother is Holly Gerke and for the longest time growing up she coached me with her Williams Pace Calculator that was like 15 years old from when she race walked. It was a greenish turquoise one which I don’t think is made anymore.
