Trek Fuel EX 9.8. Mostly sunny, cooler but humid, no noticeable winds. Started the ride early, around 7:50 am, I saw only one other rider out on the trails, a few more when I got back to the trailhead at the end of the ride. I was surprised the park was open after all the storms lately. While the main singletrack trails were open and clear, most of the connector trails had major trees down and I had to walk a huge portion of the upper Prairie trail with multiple downed trees. I ended up doing the Prairie and Marsh trails only in one direction. There was also a lot of sand wash plus quite a few greasy spots, so progress was very slow at times I ended up doing 4 trips around the Founders Loop and Big Wheel plus 2 full trips around the North singletrack trails, once in each direction. Tons of climbing. I had to wash off the bike after the ride with all the sand and mud stuck to it. Rehydration and lunch at the Hairy Cow.
