Returning to Pheriche and the race route, we climb up to the Thokla Pass through an increasingly rocky landscape to the tombstones hung with prayer flags. Here there’s a memorial to Rob Hall, the New Zealand Guide who died on Everest. Crossing the river we will be stopping for tea near control 2, before the last bit of the walk to Lobuche. There’s a good sized camping area here on the bumpy ground. We’re way up now at 4910 and there’s not much in the way of vegetation – the big mountains are getting closer and even with the sun out, we need to wear another layer.
