I just got back from a few very muddy days at Windham and, despite the foul weather, had a fun time. Windham lacks the broad array of trails that, say, Creek has, but makes up for it in the length and elevation. Even though there's about 5 legit, full length trails (plus a few side hits), there's really only 1 that's truly noteworthy and its the Gravity Logic built jump line called Windham Roll. Its about 3 miles long and has about 45+ jumps on it from top to bottom. About 40 of them are legit built tables, step ups or downs or wood ramps and the remaining few are natural rock ramp features. They are medium to medium+ sized at best but the super smooth grading, fast berms and higher trail speed coupled with the sheer amount of varied style jumps means lots of opportunity to play around.
Even though the jump trail gets all the attention, the jibby natural terrain trail is also a lot of fun but would be better on a smaller trail bike. The DH trail was way too treacherous in the wet to spend any time on. The green trail kinda sucks though as its just miles of flat turns with too many boring climbs thrown in.
Seems like that place is an untapped wonder though. The amount of real estate there is massive and the DH trails only encompass a small portion of the mountain. Would be great to see some expansion there on the same level they've done with the existing jump line.
