Turning around isn't failure.

Ignoring your body because strangers on the internet completed the trek is a much worse decision.

The mountains will still be there next year.

No dramatic story—I just wasn't enjoying it.

I'd slept badly, had a mild headache from the altitude and realised I was climbing because everyone online said Ala-Kul was "unmissable."

I walked back to Altyn Arashan instead, spent the afternoon soaking in the hot springs and honestly had one of the best days of the trip.

Sometimes we need to give ourselves permission not to finish every famous hike.

We're reasonably active but definitely not hikers.

The first afternoon we kept comparing ourselves to faster walkers who overtook us.

Big mistake.

The second day we slowed right down, stopped worrying about everyone else and suddenly the whole trek became enjoyable.

One thing I wish someone had told me beforehand is that altitude affects everyone differently. My husband was absolutely fine, while I needed to stop every fifteen minutes during the final climb.

The biggest problem isn't people's fitness.

It's expectations.

Many visitors arrive after seeing beautiful drone videos on Instagram. They imagine a pleasant walk to a turquoise lake.

What they don't appreciate is that the scenery comes because you're crossing a high mountain pass.

There are no cable cars.

There are no roads.

You earn those views.

Every season I meet people who turn around halfway because they started too late, carried far too much in their backpacks or underestimated how altitude affects them.

That doesn't mean the trek is only for athletes.

Far from it.

I've guided school teachers, doctors in their sixties, university students who'd never camped before and families with teenage children.

The successful groups all have one thing in common: they never try to race the mountain

The question isn't whether it's technical—it isn't.

The question is whether you're prepared for a couple of physically demanding days.

The climb towards Ala-Kul Pass is long, steep in places and you're above 3,500 metres. Even if you're reasonably fit, you'll probably be breathing much harder than you're used to.

When we reached the pass, there were people in their twenties who looked exhausted and a retired Dutch couple quietly eating sandwiches as though they'd just finished a stroll.

Fitness matters, but so does pacing yourself.

Everyone keeps recommending the Ala-Kul trek, but we're not serious hikers. We walk regularly at home, do weekend hikes in the Lake District, but we've never done anything at high altitude.

Some blogs describe Ala-Kul as a moderate trek, while others make it sound extremely difficult.

Are ordinary travellers completing this hike, or is it really aimed at experienced mountaineers?
