Route submitted by Olaf Soons:

The waymarked 'Darent Valley Path' is 19 miles (31 km) long, following the River Darent from the banks of the River Thames at Dartford through the Kent Downs Area of Outstanding Natural Beauty to the Greensand Hills above Sevenoaks.  The route is linear and can be completed in either direction, although traveling North is considered the easier option due to the favourable change in elevation.

The Norfolk Coastal Path was established at 46 miles in 1986, then extended to 63 miles in 2014 and to 83 miles in 2016, from Hunstanton to Hopton on Sea.

The Monumental Loop is a 305-mile Figure-8 that starts in Las Cruces, New Mexico. The Northern loop takes you through the Dona Anas, through Las Uvas and the Robledo Mountains. You return to Las Cruces, then head out on the Southern Loop to Franklin State Park in Texas, then through the Potrillo Mountains.  It is primarily a bike route put together by Matt Mason and Pablo Lopez.
