Guidebook to the Southern Upland Way, a coast to coast walk through Galloway and the Scottish Borders. One of Scotland's Great Trails, the 347km (215 mile) route links Portpatrick on the west coast to Cockburnspath on the east, through diverse landscapes and rich natural and historical interest. It can be completed in around a fortnight.

A guide to mountainbiking, cycling or walking the GTMC, Grande Traversee du Massif Central, in southern France, from Clermont-Ferrand in the Auvergne to Montpellier and Sete on the Mediterranean. The GTMC is a long-distance mountain biking trail that crosses the entire Massif Central in France visiting all of the major regions, including the Auvergne with its chain of volcanic puys in the Monts-Dome and Monts-Dore ranges, the Cezallier plateau and the remote Margeride, home of the French Resistance in the Second World War, the high forested hills of the Cevennes National Park, made famous by the Scottish author Robert Louis Stevenson, and finally the dry limestone hills bordering the coastal Mediterranean plain. Much of the route is off-road and uses many Grandes Randonnees, so it also makes an excellent walking route. Just over 700km in length it offers a challenge and a thorough exploration of one of southern France's most beautiful and historically interesting regions. The route is described in 17 stages, with maps for off-road and on-road routes, making it suitable for both expert and novice bikers, with full details of facilities and places of interest en route and other useful data for planning the trip.
