My town is having a 5k walk, 5k run, and a 10k run. I never really thought about it before, but my plan was to do the 5k walk and run at certain points throughout. Now I'm filling out my sign up papers and I don't know if I should circle 5k run or 5k walk. I will be mostly walking with some running, as this is my first 5k. Is that allowed during a 5k walk or will I be disqualified?
