My name is Jamie Mackenzie and I am proposing to run 320 kilometres from Mount Everest Base Camp in Nepal all the way to the capital Kathmandu in an attempt to break the fastest known time for the distance - currently 63 hours and 8 minutes in one continuous run. 

The run will start in late May 2017.

The aim is to raise funds to go towards school building work in Nepal.

The run follows an established route called the Everest Mailrun.

It is extreme by most standards, as the start is at 5,360 metres altitude, where the air has 50% less oxygen than at sea level, and the route includes more than 10,000 metres of ascent and 14,000 metres of descent.

The Mailrun route was used by Sherpas to transport letters on foot from climbing teams on Everest to Kathmandu and the wider world. News of the first Everest summit on May 29, 1953 by Sir Edmund Hillary and Tenzing Norgay reached the world this way, as a runner was despatched from Base Camp with a coded message - this was probably the last time news of a major event was delivered this way.

I hope you feel the attempt and cause are worthy of a little of your support, and thank you for the time taken to visit this page.
