Yes. I 100% support bicycles at the Ohio Mile. Even now that the most of the pits have moved closer to the starting line, I still think that bike is the way to go. Most competitors will have some other form of transportation to get from their vehicle to the pits / food / registration trailer (golf cart, scooter, bicycle, or lawnmower - seriously). I like getting the exercise and having the maneuverability of being on a bicycle.
Plus, with the speed limit at "10mph" through the pits, being on a bike is not going to put you in the way and will keep you in the regular flow of traffic.
