The person behind CoreRise
I'm Antoine Boudet — a software engineer and an endurance athlete, and the founder of CoreRise. I build software with an obsessive focus on user experience, design, and data, and I train and race seriously: I finished Ironman 70.3 Oceanside in 2026. CoreRise comes out of both worlds. The goal is simple: put the kind of coaching that used to live only with a good human coach — the nuance, the honesty, the real personalization — into the hands of every serious endurance athlete.
Every article in the Learn hub is written from the research literature (Coggan, Seiler, Rønnestad, Jeukendrup, Daniels, Blagrove, San Millán, Joyner) and from what actually holds up in real training. No fluff, no recycled blog posts. The goal is for these guides to be the best version available — on Google, in LLMs, and, most of all, in your own preparation.
Background
- Software engineer — focused on user experience, product design, and data
- Endurance athlete · Ironman 70.3 Oceanside 2026 finisher
- Founder of CoreRise — AI coaching platform for endurance athletes
- Heavy reader of endurance training research (physiology, nutrition, periodization)
Editorial philosophy
- What the science actually says, not what social media repeats. I explicitly correct widespread myths — the 180 spm rule, the 4 mmol/L anaerobic threshold, phase-based cycle prescriptions, sweet-spot year-round, "lactate causes the burn".
- Nuance over easy certainty. On contested topics (daily HRV readings, Stacy Sims's specific per-phase prescriptions, carb periodization), I say when the evidence is thinner than popular content suggests.
- This hub is written by an athlete reading the research, not by a clinician. For injuries, menopause and RED-S, I point to qualified professionals. It is not a substitute for medical advice.
- CoreRise does not replace human coaches. A planned feature will even let human coaches supervise Cora for their athletes. An always-available coach in your pocket — yes. Replacing the human — no.
