...in which, standing in for Mark and Dave, broadcaster Nick Brownlee ventures out with Jon Bennett – a man who has climbed Helvellyn 778 times. Ascending Mires Beck, we hear from Jon about the important role of the National Park fell top assessor – a job Jon never thought he would get – and about why, even after 16 years climbing Helvellyn, he's still not bored of it. We learn about magic times on the fell – a Brockenspectre tracking Jon over Striding Edge – and about the role walking played after the sudden death of a close friend. As we continue our ascent, we discuss tree planting schemes and pitching to protect this most loved of mountains, and picnicking beside Red Tarn, we reflect upon the unique weather conditions that impact on Helvellyn. Finally, descending into Greenburn, we marvel at industry old and new, from the towering slag heaps of Greenside Mine to the new-generation hydro scheme supplying power to the National Grid.
