It's been a couple months since I ran around Annapurna, but there's been a frenzy of activity regarding the run lately! First of, a two minute video on what it was like to complete the whole trail in less than four days (spoiler alert: it was HARD).
Secondly, Outside Magazine published a write-up of the run here - I'm not quite sure I agree with their title assessment (ha!) but I'm certainly stoked to have been able to pull off the FKT at moment's notice.
Finally, if you're an ultra runner and considering a big mountain FKT attempt like this yourself... you may enjoy the beta that Himalayan Adventure Labs published in their "Behind the Scenes" post a little while ago; I hope it's useful to you.
