Mile twenty-two of an ultramarathon. A technical ridge at altitude with a storm building on the horizon. These are the moments when the mind becomes your fiercest competitor — not fatigue, not terrain, not weather. A single thought — "I can't do this" — can hijack the body.

When athletes get injured, everyone talks about rehab timelines.

Few people talk about the hit to identity.
The loss of control.
The quiet fear that whispers, What if I don’t come back the same?

Injury doesn’t just disrupt training.

Later that year I finished the Leadville 100 run and bike just separated by a week (the bike just after the cut-off).

It all felt easy…
