🌟 New blog post ✍️ I recently finished reading Mt Everest the Reconnaissance 1935 by Tony Astill 📚 The book was interesting to me for describing the first ascent of 7,045m Lhakpa Ri by Bill Tilman and Edmund Wigram, a peak that I climbed myself in 2007 🗻 www.markhorrell.com/blog/2026/ti...

This made me laugh. Yes, me too. I remember getting thrashed by a team of Peruvian villagers while trekking the Huayhuash Circuit in 2002. ⚽ Not mentioned in this article: our football exploded while being carried up from a lower altitude. 💥 www.theguardian.com/football/202...

Thomas Tuchel’s side have problems aside from the altitude: defeat in a Mexican haze would be no embarrassment

Speaking as a high-altitude mountaineer I advise Tuchel to slow the game down against Mexico 🗻 Azteca Stadium is at 2,200m. England have just 3 days to acclimatise 🏴󠁧󠁢󠁥󠁮󠁧󠁿 The difference in performance once you're acclimatised is HUGE. If the game is played at a frantic pace, Mexico will win easily 🇲🇽

🌟 New blog post ✍️ People talk a lot about whether oxygen should be used for notable ascents at high altitude. They don’t talk so much about HOW MUCH oxygen is used, and this is crucial. 😮‍💨 Here’s my take based on my own experience of using different flow rates. www.markhorrell.com/blog/2026/fa...

Fastest known times on Everest: how much oxygen is allowed?

Record claims require scrutiny. People talk a lot about whether oxygen should or shouldn’t be used at high altitude. They don’t talk so much about HOW MUCH oxygen is used, and this is absolutely cr…

"He described how he spent 2 days there waiting for someone to rescue him. Eventually, an avalanche fell into the crevasse and with fresh snow covering part of the hole, he managed to get out." A remarkable story. The words Joe and Simpson spring to mind. explorersweb.com/abandoned-on...

This is an outstanding achievement by any criteria. But I can tell you from experience that oxygen at 4 litres/minute makes a HUGE difference to your performance, which matters if we're talking about records 🥇 explorersweb.com/tyler-andrew...

🌟 New blog post ✍️ Edita and I decided to start bagging the highest point in each of the UK’s counties 🪧 Last month, we finished the 13 historic county tops in Wales. Unlike the English tops, that include roadsides and junkyards, they are all good hills 🗻 www.markhorrell.com/blog/2026/ba...

"He had just touched the summit point and heard someone say 'you should be ashamed of yourself'." Handbags on Snowdon 👜 IMO, they need 2 summit cairns now: one for people happy to wait in line, and another for old-school folk like me who used to enjoy the scrum ⛰️⛰️ www.bbc.co.uk/news/article...

🌟 New blog post ✍️ Last year, a dog followed us for 3 days from the park entrance to the summit of Pico Duarte, the highest peak in the Caribbean, and back down again 🐶 Here’s the dog’s ascent video. You may just spot me in some of it too 📽️ www.markhorrell.com/blog/2026/my...

“Nothing beats the modest triumph of standing on top of a trig point in a brisk wind and we hope these two modern obelisks of concrete in the countryside will soon be recognised.” They should list all 6,000. It would be nice if some were more accessible too 📐 www.theguardian.com/culture/2026...
