I wouldn’t say good to go, but it’s doable out there.
I was on mount falcon yesterday and that trail had everything, snow, ice, dirt, and mud, I was just hiking but saw some bikes out there but I wouldn’t have wanted to bike it.
Waterton canyon I was out running on, did a 27 mile jog as an out and back a couple of weeks ago and the road was dry but the trail was snowy/icy once it got to the single track portion past the damn, it’s shady in this trees so I’d imagine it’s still pretty icy.
Heading to bike Matthew winters today, which is usually in shape earlier so I’m hopeful.
