Fuel EX 9.8. Sunny, warmer than forecast but still hovering around 30 degrees, moderate West wind. Snow was a bit heavier in Rockford, around 6-8" the main singletrack trails were groomed, sometimes double wide and compacted in the middle from heavy fat bike traffic. I should have arrived in Atwood 2 hours earlier as the sun was starting to soften the snow, particularly outside of the center compacted area. A very hard ride as the softening snow made the steep climbs in areas very difficult and slippery. The soft snow also made it seem like I had a balance issue but I think it was only the tires slipping. Some of the woodland access trails were groomed only and not suitable for my MTB so I had to skip the Marsh and Prairie sections. I ended up riding 3 loops of the Founders Trail, a full loop on the North Trails, starting and ending on Daisy Cutter, Counterclockwise on the outer loops then back on the inner loops of each section. I did only on trip on the Big Wheel because the uphill access was so difficult and the trail was sketchy on the downhill portion. After 1.5 hours I was pretty sweaty and worn out so I called it quits.
