Read carefully, Dear Runner. We see the event as a bonding experience. She finds them festive and fun, especially after she's finished the race. She also knows that a race is no stroll in the park.

It's proper race manners to give them the space to get by. If you must run or walk in a group, please stay in the back of the pack. That way, you'll have a chance to bond with your friends while other runners will have clear sailing to the finish. I'm working as hard as they are. Learn the meaning of the word in runners' parlance.
