Another good week of training but continued frigid temperatures

I logged 15 hours and just a bit over 6600' vertical.  I managed 149k split between exercise biking (81k), running (12k+), and nordic as well as ski mountaineering (55k+). In anticipation of a virtual 50k and the Lake Placid Loppet in the next month, I will start to increase the length of a couple of sessions per week.
