Cold (20s) and windy. The first 5 miles felt strong and fleet of foot then the right knee started talking back. I'm not sure what is going on but it is a soft tissue injury–perhaps tendon strain?
6.70 m in 1:00:12 for a 8:59 min/m burning 831 cal
Vertical +/-: 550 / 581 ft
Either way I don't feel that I should run on it even with the minimal swelling, tightness and pain (0.5 on 0-10) so I am putting myself on the injured list for at least the next two weeks. Any races I wanted to do the first half of the year will be scratched until further testing since I'm only 8 weeks away from the 50 m I wanted to attempt. Worst case I hope to salvage the running season by pacing Ultra’thoner at Lean Horse in August and then attempt my first 100 in October at the Boulder 100. Time will tell.
