I went trail riding on some snow covered single track yesterday. My mtb has 26"x2.1" tyres so I was sliding around alot. There was one other mtb 29 er possibly and one mtb with a fatty on the front, and at least one guy had a studded fatbike. Most had fatbikes IT was 10 degrees out and I needed to get back to watch football so I didn't have time to chat about their rides. The fatbikes definitely had the edge in handling but when the snow went shallow or hard enough I could catch up like a rubber band. I was spinning my rear tire A LOT. What was interesting is I could not maintain a sraite line or stay on the ridden trail to save my life but out in an open cornfield section I was better off forging my own trail in the 6" of snow. Took me 1.5 hours to go what I believe was 6 miles. It was one of the most intense fun workouts ever. After a while I got used to having no control and spinning the rear excessively but not yet how to handle the front tire sliding out.
