24.6km loop with 1,455m gain in 7:10hrs.
A bit windy at open spaces, almost no snow (as usual in the foothills & front ranges).
Solo, in complete solitude.

The best time to do it though in late October or November: no leaves, and no or almost no snow, Powderface trail is still open for traffic. Better to do with 2 cars, or at least a bike. Otherwise it'll be a long 7 km walk. Or half walk, half run - a bit faster, but feels long anyway.
