Chiltern, Chiltern, Bang, Bang (200km) & Chiltern Roalds (100km)

200km and 100km accessible audaxes with GPX that will suit seasoned and first timers alike. Passing landmarks relevant to Chitty Chitty Bang Bang and Roald Dahl (hence the names), the 200km passes through 7 counties whilst the 100km version shares the first 50k before returning home via Chiltern lanes. A mix of climbs and fast flat sections, something for everyone, puncheurs, grimpeurs, fixies and time trialists. Easy access from M25 / A40 plus 3 London Underground lines and the Chiltern line.
