We are experiencing warmer weather than normal, which is causing the snow to melt and re-freeze daily. This has led to very slippery conditions.
A few years ago, I was running in similar conditions, and I got to an area where the ice started to feel more slippery. So my reaction was to stop running and start walking. To my surprise, it was harder to walk in the icy conditions than it was to run: it felt as I was slipping with every single step.
Today, in light of the conditions, I tried the experiment again, and my sensations seemed to confirm what I felt the previous time.
Is there any physical basis to what I felt? Is it possible that running on ice produces a more stable footing than walking does?
If it makes any difference, the ice is of course not smooth, and one is usually slipping on the "slopes" of small creases.
