5ks like that are fun. I sign up for them occasionally here in Colorado because it feels like we have one every other freaking week. The blacklight run or the color run or even the bubble run was pretty cool. Runs like that arent difficult because they arent competitive. THey are fun and you can just enjoy the experience. I actually took my 7 year old to two of them and we kinda walk and jog and do whatever at our own pace. Definitely a great step towards getting fit, even if you only walk the whole thing.
