Land Owner
Official multi-use bidirectional gravel trail. The trail is open year-round to bikes as well as equestrian and pedestrian traffic. Bikes are required by OSU to yield to all other users.
The trail starts with a series of punchy climbs and quick descents over roots and often quite loose gravel through the first half. The second half is all downhill, also with roots and gravel, and a few switchback-style turns. Mind your bars on the one tree gap – it's not exactly set up for modern wide-bar setups.
Extendo is often paired with Uproute and Road 6020 to make a short loop, which means it is most often ridden downhill.
Access Info
Access the top of this trail from the top of Uproute, just alongside Road 680. Access the bottom of this trail from Road 6020, within a few hundred feet of Patterson Rd.

I love this trail, techy and challenging. I'd call it
It a blue. Several trees are down in the area after the Jan 2024 ice storm. Two blocking this trail and one uprooted took out a fun corner right before some rooty drops.

It's a pretty fun trail. Lots of roots and small root drops, a few little rocky/rutty spots. I would rate it at the higher end of beginner, It's more of an intermediate, IMO, at least compared to other local intermediate rated trails such as Bombs Away and Ridge. It's got more tech sections and bigger root gardens than either of those, IME.

Fun trail but full of poison oak, make sure you where something covering you legs!
We hope you've been enjoying Trailforks!
