You didn't lose yourself.
You just stopped looking.
This could be your wake-up call. Reclaim your Identity in Midlife.
By the time we get to Midlife we've likely been sleepwalking through Doors for years—a career that changed, kids that needed everything, aging parents who suddently needed us too— and we didn't even notice as they closed behind us.
This loss of identity in midlife impacts your mental and physical health.
G4L is taking it head on.
It's not just you.

— Jay Crain, G4L Founder
Something new. Brought you by midlifers who've lived it.
G4L is based on Boulder cyclist and entrepreneur Jay Crain's personal experience of recovering from a dire health situation—losing 100 pounds, getting off all meds—by first reconnecting with his identity as an athlete. It considers what it took for him to come back, how to overcome false starts, what is required to keep going, and what to do when you screw it all up and have to start over. Dr. Greg Welk's lifetime of teaching, publishing, research, and delivering public health programs is the science-based foundation of G4L. Jay's lifetime in technology delivers the program in a way that meets the moment.

10,000 Comebacks
That's the mission. Ten thousand people who reclaim who they are, extend their healthspan — and send a ripple to impact even more. The Charter Member Cohort is the first: a small founding group going through G4L alongside Jay who is going back through it again for himself
The film became a book. The book became an app. The app is becoming
a movement.
GRINTA! film began as a midlife project for Jay Crain and his wife, Donna. The tale of pro cyclist Eros Poli, who recovered his identity to win a stage of the Tour de France, inspired the name of the G4L program — because grit and determination are at its core. Screenings anchor G4L’s social impact strategy.
