Just wanted to direct your attention to a horror film coming out on DVD March 13th from Lionsgate (SAW, HOSTEL etc) called BLOOD TRAILS that features a young woman on a biking trip with her boyfriend who get terrorized by an insane man on a bike.
So yeah, Mountain Bike Horror. Who would have thunk?
