Flying from sea level to Leh at 3524 metres (11,562 ft), it’s strongly recommended you rest for at least 3 days. To acclimatize.

I recall doing exactly that after flying in to Lhasa 3,650m some years ago.

Instead I decided to register for the Ladakh Half Marathon. … What could go wrong?

Luckily for me they turned away my last minute US$35 registration. With nearly 4000 runners already signed up, I was one too many.

I’ll acclimatize at least 3 days before hitting the trail. After all. 🙂
