The Markermeer Loop is a very popular route around the Markermeer Lake, north of Amsterdam. It's mostly done by road cyclists but this addition here at FKT will be for walking / running attempts. The route follows the edge of the lake for its entirety, and is fully connected except for the 300m across the river IJ, and that's why the route starts north of the Amsterdam Centraal Station (on the north side after taking the pond) and finishes at Centraal Station ferry docks.

It's also an exact 160km (100miles), which makes for an interesting flat attempt at the distance.

Lagunas Altas is the flagship trail of the newly-established Patagonia National Park, a 750,000-acre protected area created through collaboration between Doug and Kris Tompkins, and the government of Chile. Lagunas Altas is a long day-hike trail near the park headquarters, with a steep ascent and panoramic views. It was named one of the “top 5 trails in Patagonia.”

The FKT route is a ~20km loop, as shown in this brochure:
