Tenzing Hillary Everest Marathon
Namche Bazaar, Nepal · May 29 · Main quest length: 1 day
The Tenzing Hillary Everest Marathon starts at Everest Base Camp and finishes in Namche Bazaar, which means the race itself is really just the final, communal high point of a journey you've already spent two solo weeks earning. Held every 29 May since 2003 to commemorate the first summit of Everest, this is the world's highest marathon by starting elevation — and getting to the start line is most of the achievement.
That's the real appeal for a solo traveler: the trek in is a premier solo bucket-list journey in its own right, and Nepal's teahouse trail culture makes doing it alone easy and social at once. You'll spend ten-plus days acclimatizing through Sherpa villages, sharing dal bhat and stories with fellow trekkers at teahouse tables each night, watching your body adjust to elevation a little more each day — and by the time race day arrives, running downhill through the villages you just walked through feels less like a race and more like a victory lap through a trip that already delivered.
Budget for the full package — permits, teahouse trekking days, guide/porter costs if you use them — but daily costs on the trail stay moderate by Western standards even as the total adds up.
