The Roller Coaster:  https://virginiatrailguide.com/2016/03/07/appalachian-trail-ashby-gap-to-bears-den-rocks-the-roller-coaster/

This section of the Appalachian Trail between US 50 (Ashby Gap) and VA 7 (Bears Den Rocks) is known as “The Roller Coaster,” as the AT climbs and descends many small ridges and hollows.

The loops starts & ends at a parking area off the west end of West Atlantic Boulevard.  The entire conservation loop is a gravel/grass trail. I would start with this loop if you have never run on a trail before. It is the shortest loop of all the conservation area loops in the glades.  Shorter is good here because the is little (potable) water, little shade, and it can get very hot.  There are only two spots during the whole route where you will find somewhere to go under for some shade. It is a very hot run if you do not start early.

Running in Korat - Pak thong chai bike lane start from in front of PTT gas station. Run along bike lane and finish at the end of the route. Distance around 9 km and 55 vertical gain. This route is popular for local runners to do long run on weekend.

Mount Olomana rises like a green fin 1,500ft out of the surrounding jungle. This striking feature, on the Hawaiian Island of Oahu, has been called, "Oahu's Matterhorn." A well-used trail wraps up the NNW ridge and involves some class 4 scrambling to reach the top. The views from the top are amazing, giving you panorama views of Kailua and Kāneʻohe Bay and across to the Koolau Ridge. This route exposes visitors to the steep, rugged nature of the volcanic Hawaiian Islands.
