I ran three times this week (normally I'm lucky to get two runs in). Two were on the treadmill, and one was a trail run as I was working from home and it was actually a warm January day - bliss! I got in about 10 miles total (each run was 3 to 3.5 miles). Unfortunately my left knee is barking a little today for the first time in ages (not really sure why, it was fine during all the runs and after them), so I am taking the weekend off from running and just doing trail walks. If my knee is pain-free, I'll try the treadmill again Monday at the gym.
