Clare Balding digs into the archives to find the most dramatic weather conditions she's recorded in; she also hears from those walkers who've had had the biggest adventures.

The highlights include: Satish Kumar who covered 8000 miles when he walked from India to North America in the 1960s, to protest about nuclear arms;
retired RAF officer, Lucy Newcombe, who has walked around the British coastline; and back in 2012 Clare found herself in the wildest of conditions on Dartmoor, luckily she was with a group from the Search and Rescue Dog Association.
