I'll get straight to the point...I am a hobby jogger. I want the opinion of all you "world class" letsrunners. Co-worker is a borderline "competitive" runner (16:45 min 5k). He thinks he is too serious to wear a flash costume at his last race. I think it would be great to see him beat other "serious" runners while wearing a flash costume. Any ideas on how to convince him? How would any of you feel if you lost to a guy in a flash outfit?
