Trap Dike is a semi-technical ascent route on Mt Colden, the "historic mountaineering route", according to https://www.adirondackexplorer.org/stories/trapdike

Car-to-car specs are about 12 miles and 2800' of gain and loss, with most of the gain on one 30-40 degree scramble on the Dike, and a steep descent on the Arnold Slide. A route map by Phil Maynard is here.

The Briarcliff-Peekskill Trailway is a 12-mile route that runs from the town of Ossining to the Blue Mountain Reservation in Peekskill. It is park of Westchester County Parks. This particular park was built on land originally acquired in 1929 by the Westchester Parkway Commission for the construction of the Briarcliff Peekskill Parkway.

"thinnmann" posted the route:

Just fell into an almost perfect 10K loop, with 1500' elevation gain in 2.9 miles.

Start in Margaretville at the Galli-Curci Theater, run up the Dry Brook Ridge Trail to German Hollow, take German Hollow Trail to Arkville, and finish the loop back to the start on NY SR-28.

I'm gonna claim the FKT for now @ an easy 1:17:10.

Nothing better to do after a snow-starved ski day....

The ski slopes of Whiteface Mtn are the location of a VK race in July of each year since 2016.

Records are kept on the race website.

On 5/30/2015 I ran the length of the Old Putnam Rail Trail from Brewster, NY to the bottom of Van Cortlandt Park in the Bronx.  I ran this 48.8-mile route solo and unsupported in a time of 6:50:12.

Breakneck is one of the most popular hikes in North America, seeing over 2,000 visitors per day on a sunny weekend. It's easy to see why with epic views of the Hudson and cliff lines all around you, just an hour from NYC. It's also quite possibly the most difficult trail mile on the east coast, not only for the vertical feet per mile, but the scrambling nature of the trail. The first 1/4 mile ascends over 500', with ample class 3 scrambling involved. It's a great mixed route, perfect for the rock climber turned trail runner.
