Well, my "non-running weekend streak" is over (see post below)...I just got back from a run. I'm glad I did, because I learned a few things and found a new trail.
I went to a snowmobile trail near our place where I probably should have worn snowshoes, but I decided instead to just use my shoes and microspikes. I wanted the opportunity to practice running on a tough surface for my Rock and Ice training. Even with the spikes I was totally spinning my wheels and not warming up very well. After 12 minutes, the toes on my left foot were starting to freeze, and it was only -10C, so I should have been okay by then. I wasn't having much fun.
In an effort to warm up, I started bounding with an exaggerated stride and two thing happened: First, within a minute my toes warmed up; and second, I started moving over the soft snow a lot more efficiently and enjoyably. A good thing to discover for R&I. I dropped the exaggeration a bit, but kept the more forefoot striking form, and it was a much better run. The slower I go, the more heel strike I usually have, and this was really working against me on the soft surface. I still need to work a lot on this stuff and be better prepared for anything.
The new trail was only a 10 minute loop, but it was so pretty as it weaved narrowly through snow-dappled pine trees.
