Running Challenges by Keri Wallace showcases 100 of the best runs across Great Britain, from inspiring 5Ks through to epic multi-day ultras. Split into three sections – England, Scotland and Wales – and featuring a mixture of marked trails, organised races and unmarked self-navigated challenges, the runs ramp up in difficulty as you go through each section, so, whether you are a beginner or a more experienced trail, fell, mountain or ultra runner, you can find something achievable, accessible or aspirational. Keri draws on her experience as a mountain runner and running guide for Girls on Hills to hand pick the best and most interesting runs across Great Britain, starting with some first-rate parkruns and short trail runs, including the Loch Coruisk loop and the Hampstead Heath circuit, working up to tough and demanding routes and races, such as the Welsh 3000s and the Bob Graham Round. Use this book to tick challenges off, or as a tool to plan where to run next – wherever you are in the UK there will be a run nearby. Each run has handy details to help with planning your adventure – start and finish points, distance and ascent, navigational difficulty, public transport, parking, route profile and overview map – along with inspirational text and stunning photography to give you a flavour of what the run is like. Other options nearby are included, along with suggestions for other similar challenges throughout Great Britain.
