HEy Kev- Congrats on signing up, youre going to have a good tiem
You can do it without pit support as it were. I think the max between fuel is 70-80 miles, I dont know for this one particularly...I know that its only a 200 mile day in total, and 70 race miles, I would have to look it up on the event schedule, but you can talk me or somebody else into carrying a gas can for you. You can leave your van at service if you wish. I ride to the start from the hotel. Technically I dont need extra gas for the day, so I'm kind of self contained but everybody helps each other out in that regard.
Its pretty self explanatory once you get there, but after a few stages, your route book sends you back to the service area for a half an hour, and this happens probably twice during the day.
