We will be hiking the 200km GR20 in 10 days which is one of the hardest high level treks in Europe bisecting Corsica from North to South. The cumulative height gain of the trek is 15,000meters which is almost equivalent to climbing from sea level to the top of Everest twice! The normal duration of the walk is 14-16 days and so attempting to do this in 10 days will be a real challenge for us. We want your support to raise money for the Duke of Edinburgh foundation. Thanks Ben and Rob
