Cold morning today (1 degrees). Since it is my day off, slept in and went to the gym later with my wife. She did spinning, I ran a MP run. 1M easy wu, 10 miles MP run for 11 miles in 1:08:40 (6:13 average). A strider for the last 0.25M at 4:36 pace (13 mph). A good run, but my back is really sore after this run. A day off with the family doing some chores and running around.
