Checkpoint. Sunny with mostly cloudless skies, cool but comfortable temps in the low 60's, ESE/East winds @ 8-9 mph with gusts around 12-14 mph. Gorgeous day, got an early start around 7:45 am, hardly anyone else out there until a couple of hours later, getting quite crowded by the end of the ride. A fantastic place to ride a bike! Once again, the Checkpoint was the perfect choice for the trip, Mackinac Island does not allow cars so the 8 mile perimeter loop was a 2 lane paradise right along the waters of Lake Huron. Rode 2 loops, once in each direction then climbed up to the roads and trails on the inner part, which included pavement, paved trails, woodland trails and gravel roads and paths. There were 3 extremely steep climbs, the first one over 22%. Finished with a 1/2 loop on the perimeter as it was getting really busy. After a quick shower, we went down to a seaside cafe across the road for lunch.
