BOZEMAN – The Bozeman area’s flat-track derby league, Gallatin Roller Girlz, is ramping up for their first home event of the season, “The Game of Throws,” a roller derby doubleheader on Saturday, May 9 at the Gallatin County Fairgrounds.

Kicking off the evening, the Girlz’ Women’s Flat Track Derby Association charter team, Mountain Mayhem, will take on Spokannibals from Spokane, Wash. Immediately following this bout, the Girlz’ B-Squad, the BoZone Brawlers, will face the Jackson Hole Juggernauts.

Armor, wielding of power, and donning the garb of the Seven Kingdoms are highly encouraged. Costumed attendees 18 and older get first crack at limited trackside seating (aka “suicide” or “nose bleed” seats). The event also features a costume contest with a prize for the best-dressed fan.

This family friendly event features food by Bubby’s Cuppa Jo, a no-host bar by Bar IX, raffles, games and prizes. The Infusion Belly Dancers will provide halftime entertainment and DJ Chachi will spin music.

An afterparty will follow the bouts at Bar IX, and a portion of the event proceeds will benefit the Cody Dieruf Benefit Foundation for Cystic Fibrosis. Visit for more information.

Doors open at 5 p.m., the first bout begins at 5:30 p.m., and the second bout starts at 7:30 p.m. Kids 10 and under are admitted free of charge. Pre-purchased tickets are highly recommended – Girlz bouts are notorious for selling out. Visit for advanced tickets. Paper tickets are available at Cactus Records and Gifts and at tart in the Emerson.

The Gallatin Roller Girlz are a 501(c)(3) federal nonprofit and achieved WFTDA (Women’s Flat Track Derby Association) apprenticeship designation last year. The Girlz are working toward full WFTDA membership – allowing for ranking at the national and international level.
