At 200 miles, it might not be the world's longest race, but Tunnel Ultra is certainly the darkest. It's a gruelling two-day endurance event where competitors run underground laps in single-file, to a backdrop of classical music. Headphones are banned but hallucinations are all but guaranteed, with sightings of abominable snowmen, giant slugs and orange blobby monsters all reported. So why do people do it? This is the story of those who do, including one who suffered temporary blindness... then thanked the race organiser for the privilege.

In the premiere season of the BBC World Service’s ‘Amazing Sports Stories’, Cassie Campbell-Pascal (Canadian Olympic gold medalist) re-visits the story of 12-year-old Justine Blainey and her fight to overturn the ice hockey establishment’s ban on mixed-sex teams. We follow Justine from her kitchen table all the way to Canada’s highest court of justice as she becomes a national hero for some... and public enemy number one for others. As the series unfolds, Cassie starts to question the narrative she was fed about Justine growing up – one that cast her in a very unflattering light.

“Yes you’re good enough, We wish we could take you. But you’re a girl.” Schoolgirl Justine’s fight for the right to play in a boys’ ice hockey team. She’s a talented player who wants to get to the top of her game. And her fight to change the rules takes her all the way to Canada’s highest court of justice. Presented by double Olympic ice hockey gold medallist Cassie Campbell-Pascall. Season 1 of Amazing Sport Stories: Frozen Out launches on 30 October 2023.
