Scratch, I dont think youll have somebody chasing you down because you didnt stop at their water station. That said, as someone who has manned a water station a no thank you or a thanks for volunteering is always nice to hear from a runner or walker though.
Speaking of water stations in Arizona, when I ran a 10 mile race the weekend before the Pig, IMHO, they didnt have near enough stations. I was starting to dehydrate and thought I was going to pass out at one point. I dont know if it bothered Pacer, Keriksen or Cactus that much but it did me. I picked the wrong day to run without my own water
I pretty much never drink during a race, at Broad St (10miles) I didn't stop at one water station. Yes, dumb, I know!!! But I always try to give a "Thanks for being out here" when I pass. Sun there was a water station 1.5miles out of the run segment of my tri. I took water for sure. And the people at that stop were amazing!!!! Cheering and yelling and so into it! THAT is how to man a water station!!!!
I have a friend who runs by the 5k water stations and says to the volunteers (with a smile of course) - "If I start taking water in a 5k - next thing you know I'll want it in a marathon..." It usually makes me laugh no matter how much I'm hurting at that point
