Tenzing Hillary Everest Marathon Training Plan

29 May 2026

The Tenzing Hillary Everest Marathon starts at 5,364 metres, at Everest Base Camp - the highest marathon on earth. You do not sign up for a time here; you sign up for the weeks of acclimatisation that make the start line survivable, and the run is the smaller half of the commitment.

What the course is actually like

The race runs mostly downhill from Base Camp through the Khumbu valley, on rough Himalayan trails, to a finish at Namche Bazaar around 3,446 metres. "Downhill" undersells it: the surface is rock and dirt, not road, the descents pound quads that are already oxygen-starved, and there is a genuine sting near the end - a climb of roughly 500 metres before the final drop into Namche, arriving exactly when nothing is left.\n\nAltitude defines everything. At the start line the air holds barely half the oxygen of sea level; pace is dictated by your lungs, not your legs or your watch, and finishing times bear no relation to road-marathon numbers. This is a trekking-and-mountaineering event with a race attached, not a marathon at high altitude.

How to train for it

The running preparation is trail and descent: long runs on steep, technical downhills to condition quads for hours of pounding, plus enough climbing strength for the Namche sting. Road mileage barely prepares you; time on rough, steep ground does.\n\nBut the training that matters most is not running at all - it is the acclimatisation trek. The itinerary builds in days of rest and graded ascent at Lukla, Namche, Dingboche and Base Camp so your body can adapt before it races; skipping or rushing it invites altitude sickness, which at these heights is dangerous, not just slow. Arrive fit, arrive early, and treat the mountain's schedule as non-negotiable.

Weather and what to expect on the day

The race is run on 29 May, the anniversary of the first ascent of Everest, and starts at 7am so the slowest finishers reach Namche in daylight. Late-May Himalayan weather is cold and variable at altitude - freezing at the start, warming on the descent, with sun that burns harder in the thin air than the temperature suggests.\n\nEverything about the day is bigger than a marathon: the logistics, the risk, the scenery, the sense of finishing something few people attempt. The photograph at Namche, not the time beside it, is the entire point.
