Notes
A long run on less hilly terrain for once (with only 1000 feet of climbing, most in the run's 2nd half), an out and back along the Clear Creek bike path, on hard-packed snow most of the way. A cold blue-bird sky morning. Went at an easy pace but still felt very tired towards the end. Pleasing though, to be able to run so far. No infamous 'wall' at 20 miles that I can see yet. Need more of these.
