So, the Roller Derby World Cup happened from 3-6 July in Innsbruck, Austria. Our hosts Fearless Bruisers Innsbruck were extremely hard working, and from the 1st to the 7th (including set up + teardown time) we worked with 6 THOs, 2 THAs, 2 THPs and three GTOs (and 9 officiating crews, dozens of announcers and photographers, and a host of volunteers, along with our streaming tech friends at Real-Time Events) to make the world's largest Roller Derby event in history happen.

Despite this record-breaking scale over 5 tracks and 80 games, each of our 48 teams only played 3⅓ games on average. In order to make it possible to effectively run the equivalent of a qualifier, "group stage" and elimination all in just 4 days - with 6 teams entirely new to Derby! - we needed to use a tiny bit of statistics.

The advantage of the stats is that we can present you with a considerably richer "final result" than most sporting events would - estimating not just final ratings but also our errors on those ratings.

Code for this graph is open to the public at https://codeberg.org/aoanla/RDWC2025 (the game data needed will be uploaded very soon).

I love that this weekend #rollerderbyworldcup was celebrated in Innsbruck, Austria, and you won’t read a word about it in traditional media. #rollerderby is one of the truest sports you will find out there, but it’s systemically ignored (I guess because it’s inclusive and run by women? Who knows).
Most important game of #RollerDerbyWorldCup? Afterparty sock derby! (Even though they’re wearing shoes)

That was SAM ROLLER DERBY (present , past, future and friends) at the #rdwc2025 ❤️💙

Congrats to teams USA🏆, Australia🥈 and England🥉 on their victory 🎉

STRONGER CONGRATS to Équipe de France for achieving their best result in the history of the #RollerDerbyWorldCup, ranking 4th place!

On entend le public dans les gradins, mais est ce que le public a entendu ma fille beugler "allééé Ta Mère !!!!" Quand la speaker a annoncé "ça passe pour Ta Mère" ? #rollerderbyworldcup

La petite finale France vs Angleterre commence dans 30 min. Puissent mes petites tornades rester à la sieste encore une petite heure pour que je puisse au moins kiffer la première période tranquillou 🤞

La team Austria, qui accueille la #rollerderbyworldcup qui rappelle les bases : Trans people belong in sport   & Skate over states ❤️
Et coucou la team SALAAM (regroupement de joueureuse du continent africain, du moyen Orient et d'Asie du Sud) qui defile avec le plus gros drapeau Palestinien que j'ai vu de ma life. #rollerderbyworldcup 🍉🛼❤️
Another upside to not officiating #RollerDerbyWorldCup today? I had time to get a tattoo of the track outline, so now I can explain referee positioning *and* use it for ORs - just by pointing at my arm 🤣 I made sure it’s placed between my wristguard and my elbow pad
Et la team Italie qui fait chanter Siamo Tutti antifascisti à tout le public pendant son tour ❤️🍕🖤
