Forty Days Across America: Andy and Tim's epic, 100-mile-a-day bike ride, from Seattle to Boston

Without a support crew, and carrying only the minimum of kit, two middle-aged English cyclists set out to ride across the vast expanse of the northern United States, from Seattle to Boston. Endlessly curious, Andy and Tim want to see everything the country has to offer - its landscapes, its people, their cultures, and their history. Packing in all the 'best bits' proves difficult, and the result is a meandering, 4000-mile route that visits Montana, Idaho, and Wyoming twice. But the pair have just 40 days to complete the ride - a punishing schedule of 100 miles a day that creates an exhilarating, unstoppable momentum.Part challenge ride, and part exploration, 40 days across America is an affectionate portrait of a magnificent and varied country of widely contrasting landscapes and cultures.
