Season One / 2026

Season One · 2026

Are you up for the challenge?

7 months. 10 chapters. 10 chances to make the deepest connections with founders who decide to suffer through something together and come out the other side. Not networking. Not a retreat. A season of challenges that leaves you with a stronger version of yourself and the people who saw you get there.

Hard Hike
CHAPTER 01 · HIGH SIERRA4 SEATS LEFT

Hard Hikein Yosemite.

YOSEMITE NATIONAL PARK, CA

Twenty miles, six thousand feet, one day. There's a stretch in the middle where you'll wonder why you came — and then the person next to you keeps walking, so you do too. We start in the dark and finish a little changed.

Dirt Biking Training Day
CHAPTER 02 · THROTTLE SCHOOL10 SEATS

Dirt Biking Training Dayin South Bay.

SOUTH BAY, CA

None of us could ride when we started either. You spend the day with patient, genuinely good instructors, drop the bike a couple times, and by evening you can ride. The easiest way in - and how you get ready for Tahoe.

Fly Fishing
CHAPTER 03 · ALPINE WATERSWAITLIST

Fly Fishingin Sierra Nevada.

SIERRA NEVADA, CA

Quieter, colder, harder than it looks. You wade in, you learn a skill that humbles everyone equally, and you stand in moving water until something clicks. Guides and gear provided. Patience is on you.

Dirt Biking Adventure
CHAPTER 04 · RIDGELINE6 SEATS LEFT

Dirt Biking Adventurein Tahoe.

LAKE TAHOE, CA

High-altitude trails and hills that many people don't think they can climb. Then someone goes first, and you find out you can too. Adventure riding, views you have to earn, and a group that's as excited as you are.

Rafting
CHAPTER 05 · WHITE WATER8 SEATS LEFT

Raftingin Wine County.

AMADOR COUNTY, CA

A raft doesn't move unless everyone pulls - that's the whole point. You'll get cold, soaked, and loud, and by dinner that night you'll know these people better than you planned to.

Hawaii
THE ISLANDSMEMBERS ONLY

Hawaiiin Pacific.

HAWAIIAN ISLANDS

The one we save for the end of the season: a week with the people you spent the year getting to know. You've probably been to Hawaii. You haven't been like this. Members only.

what makes 12SF season one

01

10 Chapters

One day you're on a laptop. The next you're somewhere with no signal and a hard thing in front of you.

02

The Challenge

Every chapter has a moment that asks more than you planned to give. The hill. The river. The last mile.

03

The Community

Seven to ten founders, hand-picked to suffer together with you. This is where the bond gets made.

04

The Film

A crew follows every chapter. You don't leave with a photo of it — you leave as part of the story.

05

The Pin and the Cap

One pin for every chapter you finish. Cross four chapters and a cap carrying a patch from every Season One event is yours. Not sold, only earned, and the others know it on sight.

Your season runs at your pace. Four pins, any months, earns the cap.
