A hair-raising sledge run - our first of this season - in the awe-inspiring Schilttal valley above Mürren.
The dry toboggan run at Pradaschier, in the southern Swiss alps, is touted as being the longest in Europe.
The lowest of the three stations along the Eiger Run sledging route, beneath the massive cliffs of the Eiger itself.
A photo and video from the Eiger Run sledge route, between the mountain-top hamlet of Kleine Scheidegg and tourist centre at Grindelwald.
Jo and I go sledging in subzero temperatures from Kleine Scheidegg to Grindelwald, along a hairpin 7.5 km route through the forests beneath the north wall of the Eiger.
In January of 2005 - five years ago this week - Jo visited me in Switzerland for the first time. These photos show our wonderful time together.
