Study links altitude headache to CGRP, the molecule behind migraine

17 Oct 20266 min read

A field study from Ludwig-Maximilians-University Munich followed volunteers from 450 metres to the Capanna Regina Margherita at 4554 metres and sampled their tear fluid at every stage. The climbers with moderate-to-severe headaches showed a clear rise in CGRP, the neuropeptide at the centre of migraine research. Oxygen saturation did not separate the sufferers from the rest. Published in Annals of Clinical and Translational Neurology.

Kilian Jornet describes losing the ability to form memories high on Everest in 2017

5 Oct 20265 min read

Speaking on Jan Frodeno's Going Mental podcast, Kilian Jornet said a stretch of his 2017 Everest climb is simply gone from his memory. He was above 8,000 metres, without supplementary oxygen, and had gone roughly 30 hours without eating. The account was reported by La Vanguardia and carried by Clarin.

Time on the mountain

31 Jul 20265 min read

Time on the mountain is the single biggest factor in whether a Kilimanjaro climb succeeds, more than fitness, more than gear, more than the season you choose. The old investor's saying goes: time in the market beats timing the market. On Kilimanjaro, the same logic holds. A longer route does not just give your lungs more days to adjust; it changes the whole character of the climb. You stop rushing. You notice things. The altitude that floors a five-day group on summit night is the altitude a seven-day group has already been sleeping at for two nights. This post looks at why the extra days matter, what happens in your body when you give it time, and how to think about route length before you book. It is the first part of our Tips & Tricks series, so it starts at the beginning, with the one decision that shapes everything else.
