We went 90 miles first day, lots of hills. Had some cramping, but that was near the end. Stayed over night at a nice place, hit the hot tub for awhile - next day was 80 miles - even more hills, but no cramps this time! Very hot, but the wisconsin back roads are great, smooth and very little trafic. Could believe how much fluids we took in. We had to time our drinking until the next town on the ride to fuel up again. Had two bottles and they went quick, lots of gu packs. Overall the ride was great, Im feeling a touch tight today, but it was fun. No flats, or mechancial problems for any of us (3) .
