That does look fun. I sometimes run downhill in my snowshoes, but I think I'd need shorter ones to run on a flat. Mine are small, woman specific, but seem kind of big to really run in.
I went for a short run-walk yesterday (2.4 miles). We are having a January thaw, and I had to get outside. It's plenty warm enough to ride, (40s), but there's sand, salt, and melting snow/ice that i don't want to deal with. It's supposed to be 60 on Sunday.
