Clare Balding helps series fan Lynda Pettit mark her 60th birthday by walking 60 different routes with 60 different people. As the idea was partly inspired by Ramblings, Clare had to join in, especially as it's her 25th year as presenter. Lynda and several friends take Clare for a hike on the Stoney Path walk in the Pentland Hills near West Linton, about 20 miles south of Edinburgh
