This is Ryan Commons.
He got it into his head to try to complete the 211mi JMT in only a week. Nuts.
Just to make it a little more challenging, he started with a pack weight of about 1/3 body weight. And climbed the highest mountain in the continental U.S. at the beginning of the adventure. (Sensible people finish on Mt. Whitney. They don’t start there.)
Many have done similar things. But none that I’ve seen have documented it so beautifully. Here’s Ryan’s 40min movie slide show of his week in the footprints of John Muir.

The JMT is our #2 best hike in the world. If you want to hike some of it yourself, check our JMT information page.

30 m/p/d is good but quite reasonable, and it’s better to start with Whitney (downhill into the Valley and all the re-supply points are toward the end). Carrying 1/3 your body weight however is definitely “nuts”, at best.
