Skated 11.25 miles in 50:55 (13.3 mph), HR 73%, temp 32. I only coughed a couple of times while skating, but immediately upon finishing my throat started tickling and I've had some coughing fits. I guess I'll have to take a few days off from cardio workouts to let my throat heal.
On the positive side, I was able to keep my feet warm by wearing the K2 Rad 100's. Two pairs of socks and my toes stayed toasty.
