More than 150 roller derby enthusiasts make up Team Crazy Legs Aotearoa and as often as possible, the team play exhibition games throughout New Zealand. As only 14 skaters are required per game, the rosters are created on a first-in first-served basis.
The roster for Saturday's game against Moana Roller Derby at the Queen Elizabeth Youth Centre in Tauranga includes seven members of the Sulphur City Steam Rollers, all of whom have experienced some form of invisible illness including depression and anxiety.
Many of those playing this weekend have spent more than half of their lives on medication, and some still struggle daily with the effects of their illnesses.
Sulphur City Steam Rollers chairwoman, Layla Robinson said she had suffered from depression and anxiety since she was a teenager.
"With the help of counselling and medication, I'm in a place where I'm okay most days, but still constantly have to fight to lift the black cloud hanging over my head. It can be exhausting.
"Roller derby gives me energy, and a positive physical outlet for my emotions. The people I've met through this empowering sport have made me feel like I'm not alone."
DeArna Branson said she has had depression since the age of 16 and also bouts of anxiety panic attacks.
"I think knowing that I wasn't the only one has helped me. I am proud to skate with Team Crazy Legs because it promotes understanding and shows that even though an invisible illness affects us, it doesn't affect our ability to enjoy life for the most part. I have found unity in this team."
This Saturday's Team Crazy Legs roster includes a mixed level of skaters from Wellington, Whakatane, Rotorua and Auckland, and promises to be an exciting game.
Team Crazy Legs last played in Tauranga in July 2017, defeating local mixed team, Space Invaders, 206-134.
Doors open at 3pm and the game starts at 3.30pm.
Entry is $10 adults, $5 children (aged 5-14), $5 students (with ID) and under 5s are free.
Duthie has created a private Facebook page for members of Team Crazy Legs Aotearoa, which is dedicated to providing a safe place for anyone who has been affected by any form of invisible illness.
