Nine days treking to the Roof of the World in Nepal was always going to be tough – and it was. On social media I said – “sunburn in the morning, a drenching in the afternoon, questionable sanitation and more privations than you could shake a stick at”. Bottled water was out of the question – not a shop in sight – so it was water from wells and streams and the filtered system of Water-to-Go was a complete blessing. Neither of us had stomach upsets and with the heat it was so useful. Thanks guys – it got us around and we got there and back without incident. And the memory of dawn over the Annapurna Ridge will stay with me for ever.
