I explored the trails at Holmberg Park this morning. What a workout. The paths had compressed snow from hikers and were 6-12 inches wide which meant I swerved into the deep snow quite often. I rode back and forth on the trails for an hour. There are some trails that are quite steep. I avoided them but I may go back in the summer when it's much more navigable. The studded tires performed well. Going uphill was a challenge because the rear wheel would spin out. I found I could power out of that situation most of the time, hence the great workout. I kept the bike in 2nd gear the entire time. I found that gear with a 90-120 cadence kept me in motion well enough and allowed me to really hammer the pedals when I needed to.
