bike-whack
v.— «We chose to take a gamble and take an old logging road deep into the forest, then bushwhack up the steep hillside to reach the Parkway.…After about a mile and a half uphill walk/ride up past a cemetery, we entered the woods again and bike-whacked for about a mile until we reached an old hiking trail that wasn’t on the map.» —“Odyssey Adventure Race 3/11/2000″ by A.J.
