Hello, my name is Harry Subertas and I’m announcing my attempt at John Muir Trail Unsupported FKT. I will start on Monday, September 28th around 6am without any support. Here is a link for tracking: https://us01.z.antigena.com/l/
And if you need my direct Garmin Inreach link: https://share.garmin.com/Feed/
Sincerely,
Hey all! Supported FKT on the JMT on 9/20. Still waiting on last minute permits, but I have one for 9/21 if it comes to that.
Tracking can be found below. Hope to go after Francois' time but Antoine is also out on trail a day ahead so we will see what happens.
I have a great crew/pacer team (including Caro who set the unsupported female FKT this summer!) coming in at Kearsarge, Taboose, Bishop, VVR, Mammoth Pass, and Tuolumne. Can't wait for round 3 on a JMT FKT, this time NOBO and this time supported.

My name is Antoine Clément, and on September 18th, 2026, I will begin a supported FKT attempt on the John Muir Trail in California.
My goal will be to challenge the current supported benchmark established by François D'Haene.
This project is particularly meaningful to me. In 2024, I crossed the United States on foot along the Pacific Crest Trail, and the Sierra Nevada was one of the places that had the greatest impact on me as a runner. Coming back two years later to attempt an FKT on the John Muir Trail feels like returning to one of the places that shaped my approach to ultra-endurance.
For this attempt, I will be running in the supported category, with a small crew assisting me at the limited accessible points along the route.
To allow the trail running community, friends, partners and followers to track the attempt in real time, we have developed a dedicated public live tracker:
