The European long-distance hiking trail E1 starts at the North Cape in Norway. It crosses Finland, Sweden, Denmark, Germany and Switzerland over a distance of around 7000 km until it finally reaches Salerno via Italy.
This route covers the German section of the E1 from Flensburg to Konstanz is described. It is about 1900 km long and is officially divided into 76 stages.

NOTE: Prior to April 2021 people took different routes traversing the park, and the FKTs reflect that.  Then, Patrick Blair very meticulously worked out the best routes for the one-way (31 miles) and out & back (actually a compressed loop with some overlapping sections, 62 miles).  From now people should carefully follow Patrick's routes if they wish to contest the FKT.  Note also that some of the previous FKTs were on longer routes, so it's not really an apples-apples comparison.

Mid Sussex Link (55km):  Brighton & Hove, E Sussex, W Sussex

North Dorset Trailway, between Sturminster Newton and Spetisbury.  About 14 miles.  The Trailway is largely made up of sections of the old Somerset and Dorset Railway which linked Bristol and Bournemouth until the 1960s.  The North Dorset Trailway Network aims to extend the trail, so the route may change.
