Almost a step too far.

The Everest 100 (October 2025)

The Ultimate Descent

Pushing The Boundaries

Descending from an altitude of 5,164 meters at Gorak Shep, to an altitude of 1905 meters at Jiri, 100 miles down the trail. With a 3500 meter pass thrown in for good measure.

This is a classic trail run through set checkpoints.

Learn as you trek.

The fact that the race is on the same route as the trek up to Everest enables runners to learn the course.


To create a sustainable annual event that will challenge athletes and to support the local communities where the event is held.

Protecting the environment

We will be limiting numbers and adhering to eco friendly tourism.

For this event to be successful it will need to protect the environment where it is held and be a benefit to the local communities.

Tourism and Commerce

We see this event as a way to responsibly develop tourism in Nepal and to create employment for Nepalese people. All money raised through this event will enter the Nepali economy and Nepalese businesses.

Sports Development

All our events have had, at their core, the aim to develop Nepali runners and to get them on to the international stage.

With this in mind we are offering cash prizes to Nepali runners to aid and sustain their development. Prizes for international runners will be in the form of momentoes.

All finishers will get certificates, medals and a tee-shirt. The first five places will get trophies. The first international man and woman will be offered a free entry into the Annapurna 100 in 2026

This map gives you an idea of the course. A more accurate map can be seen here.

Measuring a course in the Himalayas is notoriously difficult but this is as close to 100 miles as we can make it.

Kit Drops and Drink Stations.

All participants must register at every checkpoint to be deemed to have completed the event. This is for the safety of each participant and to enable us to keep track of where everybody is. Drinks and food will be provided at these stops.

It is important to have a kit bag at the finish which will be dropped off and stored at the beginning of the trek.

All of your kit that is left at Gorak Shep will be portered down and returned to you in Kathmandu.

With that in mind, it is important to understand that any valuables should be kept to a minimum and stored in a robust manner as they will be portered down.


We are not organising a dangerous event. The dangers that may arise come mostly from the altitude. The course is on well trekked paths for the most part.

That said, it is always important to know where you are: in the High Himalayas. A minimum kit list is essential to ensure you are safe from the altitude, weather, and fatigue. This is a very very challenging course. If you become incapacitated even for a short period you will need to have the ability to protect yourself. There will be other trekkers, porters and guides on the course. Help will always be fairly close. Our back up crew will find you easily as log as you check in at every checkpoint.


The checkpoints should ensure that everyone is accounted for, which is why it is mandatory for all participants to check in at them.


Between us we have been reponsible for creating and organising: The Everest Marathon, The Annapurna Triathlon, The Kathmandu Marathon, The Annapurna 100 and The Everest Ultra.

The event is based on an all inclusive package.

Trekking the course.

By trekking up the course, the runners will familiarise themselves with the terrain.

There is also another very good reason to do this. The runners will become acclimatised for the event as they trek and at the same time maintain their fitness for the event.

Board and Lodging

We will be trekking from village to village and our accommodation will be in teashops so we support the local economy. Where beds are short we will suppliment the accommodation with tents which will add to the adventure.

Board and Lodging

We will be trekking from village to village and our accommodation will be in teashops so we support the local economy. Where beds are short we will suppliment the accommodation with tents which will add to the adventure. You will be expected to have your own sleeping bag.

A kit list will appear here in due course.


Our numbers are strictly limited to 100 participants.

This is not an entry level event.

To be accepted on this event you will have to show proof that you have completed a recognised 100 mile event.

Much as people desire to take part in this event, it is important to realise that inexperience is a danger not only to your safety but also the safety of others tasked to rescue you. The first part of the race is at altitude with further climbs into altitude along the lower route.


Every participant MUST have appropriate insurance to enable helicopter rescue in the unlikely event that it will be needed. To date, since 1985 we have never needed it but cover is necessary should we need to use it.
