This is an excellent trail run course, arguably Amakusa's best. Most of the route follows a well-groomed trail, with a few km of paved road thrown in for good measure. The views are great from the clifftops and the constant ups and downs, usually equipped with concrete-log stairs, add up to a sufficiently brutal 1800m of rise (and descent!).
