Trek Farley 9.6. Cloudy at the start, sun came out after about an hour and it turned into a gorgeous Spring day, cool temps in the low to mid 60's, pretty stiff NW winds @ 12-14 mph with gusts in the mid 20's. Lots of people out today on bikes and walking, saw one deer. I rode the whole Long Prairie/Old Stone Bridge trail, all the way from the trailhead East of Capron out to the other trailhead at Rockton Rd just North of Roscoe. Lots of long gradual climbs and descents @ RR grade. Mostly head/cross winds on the way out and the opposite on the way back. Trail was about 22 miles gravel, 18 miles old crappy pavement, next time will be on the Seven as I've ridden in the past. For an old boring rail-trail, this is a beautiful ride. I went an extra 2 miles out past Roscoe to Rockton Rd for the first time - there is a convenience store at 18 miles but I just kept riding and did the whole ride without a stop. Having the Thule hydration backpack really helped. I averaged 12 mph for the first 20 miles out to the Stone Bridge Trail Head, 13 mph on the return for a 12.5 mph average overall for 40.5 miles - my longest Fat Bike Ride yet. Great workout and about 3:15 ride time.
