Burn Slush! The Reindeer Grand Prix
Competitive reindeer-racing is a popular sport in the Arctic Circle. In Finland, the season runs from November to April and good jockeys are local celebrities. They need strong biceps and serious guts - strapped onto cross-country skis they're hauled behind reindeer at up to 60km/hour. Cathy FitzGerald travels to Lake Inari in the snowy north of Finland to find out more about the sport.
Presented and produced by Cathy FitzGerald.
