The immense cathedral-like spires of the Northern Dolomites are the perfect venue for tackling one of Europe’s classic long distance treks. Forget about luxury hotels, the only accommodation is in mountain huts, known as Rifugios and I’ll have to carry everything on my back. Walking the Alta Via 1 in the Dolomites runs for around 140 km and my eight day walk will involve daily distances of between 9 and 16.5 km, with ascents of up to 900 m and descents of up to 1,300 m. Will I be tough enough?
