Jamie Ross Mackenzie is aiming to run the full distance of the Everest Mailrun route in one continuous attempt.
The start will be at 7am local time on May 29 at Base Camp on the Nepalese side of Everest. The start of the Mailrun Challenge will coincide with the full Tenzing Hillary Everest Marathon and will share the same 42.195 kilometre route down to its finishing point at Namche Bazaar. This will add nearly five kilometres to the overall Everest Mailrun route, taking the total distance to closer to 325 kilometres.
Jamie has completed the marathon route twice before, in 2012 and 2013, but this time he will keep on running on the trail from Namche Bazaar to Jiri and then continue on asphalt roads all the way to Kahtmandu.
The target is to record a fastest known time for the route.
The overall run will be primarily solo, but as part of the marathon route there will be co-runners on the course and support from the marathon crew. The section from Namche Bazaar to Jiri will be mostly solo, with some aid stations at key points. The long road section from Jiri to Kathmandu will need to be supported for safety reasons, and also to provide aid en route and to verify the attempt. The finish will be at the gates of the Rangasala Stadium in central Kathmandu.
Jamie is attempting the full Everest Mailrun to raise funds and awareness for the work of the Himalayan Trust. The aim is to highlight the need for donations to help with the reconstruction work after the devastating earthquake of April 2015, which killed nearly 8,900 people, injured 100,000, and destroyed 600,000 homes and 30,000 classrooms across the country.
