Why HYROX athletes plateau, even with intense training
In HYROX, your body is challenged on multiple fronts: cardio, muscular strength, energy metabolism, nervous recovery. Two athletes following the same programme can achieve very different results.
01
Persistent fatigue despite rest
02
Inconsistent race times from one event to the next
03
Recurring injuries with no apparent cause
04
Performance plateau despite the investment
They tried Lucis and they're not going back.
HYROX athletes of all levels use Lucis to identify what holds back their progress and optimise their preparation.
I had already done blood tests, but more standard and less in-depth. With Lucis, I found the holistic approach I was looking for, with more precise analysis and concrete optimisation leads.

HYROX Athlete
The Lucis assessment covers over 110 biomarkers, a significantly more in-depth analysis than a standard check-up. Invaluable visibility to adjust preparation and avoid overtraining.

5 biomarkers that make the difference in HYROX
Lucis measures what your body hides inside, where training alone is not enough.
Ferritin
Low ferritin = collapsing cardio, heavy legs, slow recovery.HbA1c
Poor sugar management = energy crash mid-effort, long recovery.CRP
Persistent inflammation = overwork, chronic soreness and plateau.Vitamin D
Deficiency = unexplained fatigue, frequent infections, diffuse pain.CAR
Imbalanced cortisol = exhaustion, limited progress, high injury risk.
