well I just got in from my first ride. Before my back surgery I had gotten up to riding 25 miles at a time on my Big Dummy. I purchased the cross check just a few days before I got hurt so I haven't even had a chance to ride it. Temps today are in the 50's and probably a 5-7 mph wind. I was only able to ride 7 miles in about 40 minutes of riding. Man I'm in terrible shape. It's going to be a LONG recovery.
