nope no experience of riding there. Did a road trip from Vancouver to Inuvik years ago though. God’s own country. Each province gets better as you drive along. Wouldn’t worry too much about the long days.. more riding to be had!! Watch for bears.
Pinkbike carried an article a few years ago with James Doerfling in the Yukon via Boreale Biking seemed to be the go to guys.
The Yukon and the Dempster … Robert Service summed it up beautifully
….There’s a land where the mountains are nameless,
And the rivers all run God knows where;
There are lives that are erring and aimless,
And deaths that just hang by a hair;
There are hardships that nobody reckons;
There are valleys unpeopled and still;
There’s a land—?oh, it beckons and beckons,
And I want to go back—?and I will….
