Fuel EX 9.8. Cloudy, cold - 26-30 degrees, some wind but not that noticeable on the trails. Solo early morning ride, 8:30 am roll time. I saw 5 deer but no other riders, just a couple of trail runners and some dog walkers. Ground was pretty much frozen for most of the ride, some open dirt areas but they just looked wet, no tread marks or transfer to bike tires - finished clean. Lots of snow and/or ice covered sections which I tried to stay in. At about the 90 minute mark up in the prickley prairie, the dirt started turning to mud in sections so I jumped off the last bit of trail out to the paved section. Extremely slow going for most of the ride as I had to pick my line to dodge mud and there was a lot of ice. As usual, the studded knobbies worked great but they sure add to the workout difficulty.
