Here's a quick and handy guide on building yourself a fun and maybe even an award winning running costume that should help you enjoy the sport of costume running, get some laughs and end up a picture or two. It's important to be a good sport at all times. It's ok to not talk, you're in costume after all. People want pictures so be ready to pose.
Some people can ask silly questions over and over again so be prepared to have silly answers.
Just answer the best you can if you're not sure and keep going. People need to see you coming so they're ready to take a picture when you get there. The more outrageous, the better. In the Examiner Bay to Breakers anything absurd can get a laugh, but in the Run to the Far Side, you have to be a Gary Larson inspired character. There are now many costumed runs throughout the world and I have made a costumed runs list.
