On 1 January 2025, Eli Iserbyt won the GP Sven Nys in Baal. His 54th elite cyclo-cross victory. He was 27, in the prime of his career, and nobody watching that day could have told you he had six weeks of racing left in him.
Six weeks later he stopped his season because of pain in his left leg. Everyone, including the doctors, thought it was a muscle problem. It wasn't. An artery in his pelvis had narrowed so much his leg wasn't getting blood during efforts. Four surgeries. Fifteen hours on the operating table. One attempted comeback. Another relapse.
On 8 January 2026, multiple doctors told him he had to stop. Not just stop competing. Stop riding. The sport he had spent his entire life inside of. He's 28.
This conversation is recorded three months after that announcement. It is not a comeback story, he is not coming back. It is not a greatest-hits retrospective, he still can't watch his old races. It's something harder than either of those: a conversation with someone standing at the junction between real grief and real possibility, with the road behind him closed.
Brent sits down with Eli to talk about what happens when your body ends a career your mind didn't agree to end. The misdiagnosis. The four surgeries. The moment the right specialist finally said "it's not your muscle, it's your artery." What it's like to watch your sport from the analyst's chair when you can't ride home afterwards. And the question that sits underneath the whole episode: could better data, earlier, have changed any of this, for him, or for the next Eli?
Brent knows this territory more than most. He nearly died from misdiagnosed Crohn's. Eli lost his career to a condition misdiagnosed as a muscle problem. Same gap. Same cost.
What you'll hear:
- The first time the pain hit, and why everyone thought it was nothing
- Why "Piriformis syndrome" became the diagnosis that cost him a year
- Inside four surgeries and one failed comeback
- What his data was actually showing before anyone knew what to look for
- Racing a generation against Mathieu and Wout, and what that really felt like
- Who you are when the training plan you've had every day for 15 years disappears
- What he'd say to the version of himself who won in Baal on January 1st
- Whether professional sport is actually health, or just looks like it
