I have a bit of a moral issue here. I'm not racing yet but I want to run a few time trials during the summer to gauge what kind of shape I'm in. So, is it wrong for me to run my time trials during local 5ks? I have no intention of taking any prize and while I'm running near the front of the race I'm only running about 17 minutes and so it's not like I'm interfering with the runners trying to win the race. At the same time 20 dollars is a lto of money to pay for a clock and mile markers. So what do you think? Is it ok to run w/o paying?
