Ronald Turnbull is a walker, writer, photographer and bivvybag sleeper based in Southern Scotland. In 1995 he won the Fell Running Association's Long Distance Trophy for a 10-day run over all the hills of Southern Scotland – a journey of 450 miles with over 90,000ft of ascent. His special interest is in multi-day backpack trips over rough country, and he has just completed his 21st coast-to-coast journey across the UK: a crossing of the Highlands from Knoydart to Aberdeen. Author of the minor classic 'The Book of the Bivvy', he likes to sleep out without tent on UK hilltops, and has achieved comfortable nights on 73 separate summits.
Ronald has won the Outdoor Writers' and Photographers' Guild awards seven times, in four separate categories, including Best Guidebook for 'Coast to Coast Trail Guide' (1998) and Best Outdoor Book for 'Coast to Coasting' (2000, co-author with John Gillham), 'The Book of the Bivvy' (2001), 'Life and Times of the Black Pig' (a 'cultural biography' of Ben Macdui, 2008) and 'Granite and Grit' (a hillwalkers' guide to the UK's mountain geology, 2010). 'Long Days in Lakeland' from Grey Stone Books was highly commended in the Lakeland Book of the Year Award.
