4 more subzero miles this morning. Thought it was -2, but afterwards I turned on my truck and it said -8, so I'll go with that. Wore lighter layers today and it felt much better, and I also left my microspikes at home and I ran fine without them and much lighter. Much easier run, but still challenging. Maybe when it warms up I'll be running better, but had to stop and walk at 1.25 miles. Rest of the run went well, and was again sweating like crazy after, even with only 2 layers of clothes on. The body is certainly a furnace factory. This should be the last subzero run of the winter, but looking forward to the above freezing runs which should be coming soon.
