Why I needed a build-up at all
In early August 2025 I went at the Hörnli Ridge with close friends. We turned around at about 3,800 m, roughly 600 metres above the hut and a long way short of anything.
My honest read on it, a year later:
- We had never climbed together. Not once. We trusted each other as friends, which is a completely different thing from being able to judge each other on exposed ground.
- I did not have the technical skills the route needed. I had altitude experience. That is not the same currency.
- As a group we were underprepared physically, and more importantly underprepared for the exposure.
Great friends and reliable ropemates are different qualifications.
Nobody got hurt and we made a good decision on the day. But the failure was specific, which means the fix could be specific too.
Which peaks should you climb before the Matterhorn?
Here is what we did, in order, in August 2026, with Anthony Bracegirdle:
- Üssers Barrhorn, 3,610 m. The highest summit in Switzerland you can reach on a marked trail.
- Weissmies, 4,017 m. The first 4,000er of the week and the first real glacier day.
- Breithorn traverse, 4,164 m. The test piece.
That is a ladder, not a list of nice days out. Each one adds something the previous one did not have.
What each one was actually doing
Barrhorn: altitude with nothing else going on
A marked trail to 3,610 m is an unusual thing and it is super useful. You get a big day and real altitude with no rope work and no technical difficulty to distract you. It is a pure fitness and acclimatisation session. Nothing else is being tested, so nothing else can hide a problem.
Weissmies: the first 4,000
Crossing 4,000 m is a mental step as much as a physical one, and Weissmies clears it by 17 metres... just. Glacier, rope, crampons, an early start. This is where you find out whether the altitude is actually in your legs or whether you just had a good day on the Barrhorn.
Breithorn traverse: the one that answers the question
The traverse is the test piece, and it is the one that matters. It is a long day on a ridge with sustained exposure where you and your partner have to be able to move together. That is exactly the thing I did not have in 2025.
If the traverse goes well, the Matterhorn is a reasonable next step. If it does not, you have found that out at 4,164 m on friendly ground rather than at 3,800 m on the Hörnli with a guide and a hut booking already paid for.
The partner who pulled out
After the traverse, Anthony decided not to come on the Matterhorn.
I want to be clear about how I read that, because it looks like the sad ending and it is not. A partner who finishes a 4,164-metre traverse, assesses his own limit accurately and says no is exactly what I was missing the year before. The build-up worked. It gave him the information and he acted on it.
That is what these weeks are for. They are not a training block you tick off. They are a decision-making tool. Sometimes the output is a summit and sometimes the output is an honest no, and both are the system working.
I went on to the Hörnli with a guide, Emmanuel Julien of Zermatters, on 24 August, and we were the first party on the mountain that day. Up in about 3 hours 20, against a standard guided allowance of four to five. Not bad for someone with no technical skill worth the name twelve months earlier...
How do you build your own ladder?
If you are pointed at an objective that scared you once, this is the shape I would use:
- Diagnose the actual failure, not the feeling. "I was not ready" is useless. "I had no technical rock skills and had never climbed with these people" gives you something to fix.
- Isolate one variable per day. Altitude first, on easy ground. Then glacier and rope. Then exposure and moving together. Do not stack them.
- Finish with a test piece that shares the objective's hardest quality. For the Matterhorn that is sustained exposure on a long ridge, so the Breithorn traverse. Not the biggest peak you can find, the most similar one.
- Climb with your actual partner, in advance. This is the one people skip and it is the one that ended my 2025.
- Let the build-up have the authority to say NO. If it cannot cancel the trip, it is not a test, it is a warm-up.
Three peaks, one honest withdrawal and one summit. I would do it exactly the same way again!
