Woof - that's a lot of miles to cover; was it all like that trail?
One of the crazy things out here - when we head over to ride the central Oregon desert, knocking out 70 miles isn't all that much. However, switch to the coastal range where it's a ton of up and down and much tighter - doing 70 miles would be a stretch at best (though the ISDE they're holding next weekend is 110 miles...now way could I do that).
some of the trails were like that but also a lot of open fire roads and quad trails, you could see the whole place on easy trials, but the hidden parts took going down the trails like the one in the video
