The St Magnus Way is a pilgrimage route through mainland Orkney. Inspired by the life and death of St Magnus, Orkney's patron saint. It has a range of terrain to run from rough coastal, inland tracks, moorland, hill climbing to tarmac. Even a very short forest path (rare for Orkney)! A very good app accompanies the route and keeps you on track as you go. https://www.stmagnusway.com/advice/the-st-magnus-way-app

Running/Hiking/Biking route from Berlin Center to Bernau city goes along Panke river. 

Quite scenic route. 

There is a bike repair station directly in the middle of the route on 14th km.
