Grade progression made readable
The judo federation is one of France's largest (~600,000 members). White-to-black progression is the heart of the practice — your profile records it as the spine, not a footnote.

Kelenz for your sport
From white to black belt: your judogi tells your story — so does your profile.
« From white belt to black, your judogi tells a story — your profile too. Grade progression at the heart, not in the footer. »
01What changes
The judo federation is one of France's largest (~600,000 members). White-to-black progression is the heart of the practice — your profile records it as the spine, not a footnote.
Combats, wins, losses, ippons, medals: the standard grid is handled natively, by season.
Every judoka and sensei gets an indexed public page — senior, U19 junior, veterans, women's. Achievements and results readable season by season: fights, competitions, grade tests.
Judo isn't a fighter marketplace. It's a dojo, a sensei, uchi-komi partners. A Google-indexed profile, and the connections that make a career: the training-center sensei spotting a U17 in the -66 kg class, the regional coach picking a squad for the team championships, the neighboring dojo looking for a training partner in your weight class. One request, and you're talking.
02By profile
From the U19 brown belt prepping for shodan to the head sensei of a regional dojo — here's what Kelenz delivers for judo.
U17, U19, senior or veterans? Your profile aggregates current grade, weight class, career history, fights and medals — judo identity made plain, the one a training-center sensei actually reads.
Document every season, every dojo, every grade delivered, every judoka you brought to the French championships.
