I don't think you will have any problem. We are in Richmond, and have worked the finish, it's really amazing to see people come in. Last year a 71 year old man finished at the 10 hour mark - awesome. Everyone hates the last hill, about 9 miles west of the finish, it's almost a mile long and might hit 5% grade, maybe 3% avg. The heat was the killer last year, hoping for cooler weather this year. Water will be your main concern, you may need to buy some along the way. DH added a rear tri bottle holder to carry 2 extra bottles. He did his first century last week training for the RAIN, everything went well, but he wishes he was faster. He doesn't plan to eat at the stops but rely mostly on Perpetuem from Hammer Nutrition and maybe a couple bars and some gel. A lot of the local riders have done it around here, many in under 7 hours, DH is shooting for 10 hours. Most say is mostly mental, but hydration and nutrition are key. Figure out what works for you and go with it, Hammer is excellent, if you are looking for good products. Anyway, you live in IN, gotta to it at least once. Best of Luck.
