Yes and No to No Os and Runners
After 13 hours on the move, we reached Camp 4 at the South Col. Although we may have been able to summit, we knew the descent would have been too risky due to fatigue, altitude sickness, and my partner, [Nicolás Miranda,] not feeling well. We decided to return to Base Camp nonstop.
FNT – Valid or Not, after use of Os?
I reached out to Billie Bierling, the lead of the THG Himalayan Database, to ask whether Tyler’s use of supplemental oxygen during the “trail” run disqualified his actual no O’s real attempt. Her response:
It is true that in Elizabeth Hawley’s time, we did not accept an ascent without bottled oxygen if the climber had used supplemental oxygen during the same expedition. However, at that time, the question of making one ascent with oxygen and a subsequent ascent without it hardly ever arose. Most climbers attempted only one mountain per season and generally made just a single summit push on that mountain. Moreover, those climbing without bottled oxygen were usually purists who would not even consider putting on an oxygen mask.
When Ryan Mitchell arrived at Base Camp and required bottled oxygen for medical reasons, our view was that he remained on the same expedition, having already used supplemental oxygen due to illness. Under those circumstances, it did not feel appropriate to recognize a subsequent ascent as oxygenless had he continued his climb. However, Ryan Mitchell never contacted us directly to discuss his case, which we would have been very willing to do.
When Tyler Andrews contacted us with his request, we revisited the issue within the Himalayan Database team. We also consulted high-altitude specialist Professor Dr. Mike Grocott regarding any possible physiological advantage gained from prior oxygen use. His view was that there is no real evidence for a significant physiological advantage. Based on these discussions, we concluded that we needed to adapt to modern climbing realities and accept an ascent from Base Camp to the summit and back to Base Camp without supplemental oxygen, even if oxygen had been used on a separate climb within the season.
As Professor Grocott noted: “It seems to me that it may be easier to make a subsequent ascent without additional oxygen if you have already climbed the same route with supplemental oxygen, but this is from a climbing and psychological perspective rather than a physiological one. It is very difficult to know the definitive answer to this question, but I would say it is the physiological equivalent to a Redpoint ascent.
Wednesday, May 27, 2026, Summits – 50+
Garrett Madison moved past Dave Hahn at 15 and behind Kenton Cool at 20 to second in most non-Sherpa summits, his 16th. He had a good climb:
Hey! This is Garrett checking in for the Madison Mountaineering Everest (8848m/29,032ft) team.
We have great news to report… Today, the last members of our expedition, Everest team all reached the summit! That’s myself, Jeff Arnold, Terray Sylvester, Reid Tileston, along with the incredible Sherpa team: Siddhi Ghising, Mani, Ardi, Hira, and Santosh. And we are all back in Camp IV (7900m/25,919ft) now, safe and sound, resting, recovering, and planning to head down to Camp II (6500m/21,325ft) and base camp (5364m/17,598ft) the following day.
(We) had a great day! The weather cooperated, winds dropped down, and we had some great views on the way up. It was a little cloudy up top, but not crowded at all, and we just had a wonderful time up there. A great way to conclude our expedition with all the members that were up here at the South Col, and going for the summit, topping out on Everest!
So, been a fantastic expedition, and we will check in soon.
- Madison Mountaineering – 2 members, 2 Guides with 5 Sherpas for 9 summits
- Elete Expeditions – 9 members with 28 Sherpas for 37 summits
- Summit Climb – 1 member with 1 Sherpa for 2 summits
- Seven Sumits Treaks – 1 member with 2 Sherpas for 3 summits
Summit Climb made these confusing reports about the night of May 26th and early hours of the 27th.
At around midnight winds increased and it begins to snow. We feel surprised; this is outside the parameters of our weather forecasting tools. by 1 am the bad weather has increased and 6 of our members and 6 of our Sherpas decide to descend. This no longer feels comfortable for them. Now 1 member and 1 Sherpa decide to continue on. They don’t want to descend just yet and keep climbing to the summit. 6 members and 6 Sherpas return to the South Col. 3 members and 3 Sherpas continue down to Camp 2. Three members and three Sherpas remain on the South Col. They want to try again to reach the summit tonight. Thanks for following.
Just now, one of our 3 members and Sherpas who were trying ,radio called from the summit to say they are on top now. CONGRATULATIONS. Now we are awaiting news from our final 2 members. We will let you know as soon as we find out!
Just got the news on the walkie talkie from High Camp South Col: one of our members and one of our Sherpas was notfeeling well during the middle of the night and the two of them descended back down through the darkness to South Col where they are safely resting now. Our final member and his Sherpa trying to get to the summit now, with safety.
Our final member and his Sherpa summited Everest just now at around 11am. CONGRATULATIONS!!!!! Now everyone is coming down
Later, they posted that they had found a lone climber at the South Col in a tent with no food, water or oxygen. His team is unknown.
Tibet Side Climbing
China closed its side of Everest, Cho Oyu and Shishapangma to foreign climbers for reasons unknown. However, there are Chinese climbers on the Tibet side, and as usual, we haven’t received any updates. But I hear through the grapevine that there were summits in windy conditions and complaints about the leadership.
