Whiteface is a mighty mountain, (5th highest in NY, at 4638 ft.), and perhaps the most unique of the 46 high peaks in New York, because it is so accessible. It offers many ways to summit it’s crowded and overpopulated peak. There are two different routes to hike up, or you can simply drive your car up the Whiteface Memorial Highway, which snakes its’ way up the Northeastern slope. It is almost all by itself, a lonely peak separated by the rest of the 46 peaks, with a world-famous ski resort on its’ eastern side.

24 miles in total. You run out to Grey Owl’s cabin and then turn around and run back to the start. The trail is full of rocks and roots and lots of ups and downs, which make for some tricky technical running most of the way.

The Cache Dash is a 26.5 mile horse shoe route, following the ridge and tagging the high points above the town of Jackson and Cache Creek canyon, starting up Josie's Ridge and ending by descending Crystal Butte at the Nelson Trail Head. The Cache Dash begins at Garaman Park and ascends Josie's Ridge. From Josie's Ridge you link to the Skyline Trail until it intersects Game Creek Trail, at which point you begin the off trail bushwhacking section to gain the ridge again.

The Norris - Scenic Death March Traverse (aka Chuck Norris's Scenic Death March) is a loop adventure in Glacier National Park connecting the Norris and Scenic Death March traverses, starting and finishing at the Saint Mary Falls trailhead. It is an exceptional combination of trail running and off-trail scrambling through Glacier's inspiring scenery. With careful routefinding the route goes at no more difficult than class 3. It has some fairly irredeemable sections of chossy rock that make for difficult sidehilling or descent, but overall the highs of the route far outweigh these lows. 

Mt Mitchell (6684') is the highest peak in the eastern USA.

The ascent from Briar Bottom is gains nearly 3700' in about 5.25 miles.  Start at the Briar Bottom TH, for the ascent time stops at observation deck.  While there is a Strava segment for this, it is important to report your actual (watch) time, as relying on GPS can be off by many seconds.  Also, the Strava Segment doesn't go to the actual observation deck.
