🇧🇷 Clarisse Vallim

The women's 70 kg category is a middleweight, and at cadet level it is where physical maturity varies most: a fifteen-year-old and a seventeen-year-old at the same weight can be built entirely differently. That is the first thing to understand about Vallim's title. She is at the young end of an under-18 band that runs three years wide, and she is competing there as the top-ranked athlete rather than as a promising junior finding her level.

Her judo is built on grip. She has unusually good sleeve control and uses it to set up seoi-otoshi — a dropping shoulder throw — repeatedly and hard. In the semi-final against Ukraine's Diana Samoiliuk she landed it for ippon after roughly thirty seconds. That was the pattern of the whole tournament: she won every contest before the final by the maximum score, which in judo means she never once had to defend a lead.

The final, against Belgium's Valerie Tombou, was different, and the honest description of it is not flattering to either fighter's highlight reel. Tombou, ranked fourth in the world, knew she had to neutralise the Brazilian's grip and spent normal time trying, picking up two penalties in the process. In golden score she came out more aggressive, refused the grip more forcefully and visibly put Vallim under pressure — and then took a third shido after almost seven minutes of total fighting time, which ends a contest automatically. Vallim raised her hands and smiled at her coach. She won a world final on her opponent's penalties, not on a score of her own.

That coach is Maria Portela, a three-time Olympian at the same weight, and the arrangement says something about how Brazilian judo has organised itself: a fifteen-year-old at 70 kg being cornered by a senior who spent a career at 70 kg. Vallim fights out of Clube de Regatas do Flamengo and the Judô Rio structure. “I feel so grateful to my technical staff, my family and especially my mum, who never let go of my hand,” she said afterwards. “Honestly, it hasn't even hit me yet because it's such a huge achievement. During the competition, I just told myself, ‘It's just one more fight.'”

Brazil finished third in the overall nations table at the championships and were runners-up in the mixed team event, where Flamengo's Manuela Maia was also in the squad. The Brazilian confederation has already named Vallim as the country's judo representative at the Dakar 2026 Youth Olympic Games — a single-athlete berth, which means the selection is as much a statement about her as the medal is.

The caveats are the usual ones and they are not small. Cadet is under-18; two cadet world titles do not predict a senior career, and the list of double cadet champions who never medalled as seniors is long in every judo nation. The IJF published its report on the 70 kg final on 23 August, while the Brazilian federation and Judô Rio both date the final itself to Saturday 22 August; the individual competition closed on the 22nd and the mixed team event followed on the 23rd.
