At the start, provide a small duffle bag with your name on it. For the 400 km brevet, you will see your bag at the lunch spot in Arivaca, about half way through the ride. For the 600 km brevet, you'll see your bag twice at the Elgin Club: the first time in mid-afternoon on your way to Tombstone and again when you stop to sleep or pause there in the evening. Your bags will arrive back at the finish when the checkpoint closes, and may not be at the finish when you arrive.
