Note
It was coldish and enough wind to cut away at any remnant pockets of warmth. Since my skis were waxed for much warmer conditions, I knew glide would be nil, if that, so the plan was to go out and ski classic style for a half hour or so, and then run. The plan fell apart in the parking lot when I went to get my skis and poles, and realized I had poles. Only poles. You have to be really good to ski with just poles and no skis, and I'm not nearly that good. So, running! ; )
The wind was really whipping around and skiing would not have been all that much fun anyway, so really it worked out for the best. I wore two knit caps, a neck gaiter, extra warm gloves, thick wind pants, super troja under my jacket, and a good attitude. Of all those things, the most important thing by far was the good attitude. Though the other things were good, too.
I ran snow bike trails almost the whole time. In most places some amount of snow had blown into the trail, and in some places the trail was totally obliterated by blown in snow and indistinguishable from the adjoining terrain--until you stepped off the invisible trail, and sank in to your waist. I tried my best to stay on the trail, but if I had seen someone in one of those sections, I would have deliberately left the trail and floundered, trying to make it look like a horrible snow monster had me.
I was out for about 140 minutes. For the first 90 minutes or so I had good sun, so it all felt relatively benign. But once the sun went down, I was quickly reminded it was pretty cold out. One mountain biker passed me at at dusk, but otherwise once I left the ski trails, it was a solo experience.
