I rode on snow yesterday with my riding buddy, got started at 6:30am and had a heck of a hard time. He sure made it look easy as I struggled to catchup. The lungs burned, my heart beat through my chest, it was a crap show. I walked a lot and after 45 minutes I quit. He kept on as I walked home with my tail behind my legs. It won't be long before I will be on dirt!
