The grandson of a prominent Senegalese politician, Gueye founded his country's ski federation and for a long time was the only member.

In 2017, he spoke to Tayo Popoola.

The Elfstedentocht is one of the toughest sporting events there is. It’s an ice skating race around the lakes and canals of the northern Dutch province of Friesland – and it can only take place when it is particularly cold.

The last one was in 1997, but the most notorious happened back in January 1963, when only 69 of the 10,000 skaters made it to the end of the 200 km course. The rest were stopped by the appalling weather conditions.

One of the few to complete the race was the then 24-year-old skater Leffert Oldenkamp. He tells Matthew Kenyon about the extreme race.

In 2000, Sven-Goran Eriksson got the job as manager of England’s men’s football team. He was the first non-English person to do the job.

Some in England were sceptical about an overseas coach when Sven moved from his post at Lazio in Italy to succeed Kevin Keegan as England boss.

Sven tells Uma Doraiswamy about the media’s reaction to this sporting first, his quest to understand the Liverpudlian accent of some of his new players and how it felt to go out of tournaments on penalties.

The Swede led England to the quarter-finals of the 2002 and 2006 World Cup and 2004 Euros.

He spoke to Sporting Witness a few days ago, on the day he told the world that having been diagnosed with cancer he has, at best, a year to live.

In the 2004 Athens Olympics, Brazilian Vanderlei de Lima was leading the Men’s Marathon with six kilometres to go. What happened next shocked the millions of fans watching and propelled Vanderlei into becoming a universal role model for sportsmanship.

In 1970, Yuichiro Miura became the first man to ski on Mount Everest, starting from the height of the ‘death zone’, an elevation where there isn't enough oxygen to survive for long. His daring ski run saw him reach a speed of 160 kilometres per hour, before he crashed into a boulder and narrowly avoided falling into a crevasse.

Not satisfied with this achievement, he also became the oldest person to climb the mountain when he was 80 years old.

He spoke to Emily Uchida Finch about his experiences on Mount Everest. This is a Whistledown production for the BBC World Service.

Caster Semenya was just 18-years-old when she won gold in the 800 metres at the 2009 World Championships in Berlin.

Her victory was controversial because the South African runner was facing questions over her gender. So much so, that she was made to take a gender test on the eve of the final.

The test revealed that the teenager had been born with internal testes and no womb. It meant she had higher levels of testosterone; a hormone that increases muscle mass and strength.

She has been speaking to Matt Pintus after the launch of her memoir, The Race to Be Myself.

In 2003, arguably one of the greatest tennis players of all time, Roger Federer won the Wimbledon Men’s title.

Aged just 21, it was his first major win and was the start of a record eight men’s single titles at the championships. Uma Doraiswamy goes through the BBC and Wimbledon archives where the Swiss champion looks back on his momentous win.

In December 1993, EA Sports released Fifa International Soccer, also known as Fifa 94.

The football game sold half a million copies in its first month and went on to become a cultural phenomenon.

In 1978, first division football side West Bromwich Albion became the first professional British club to visit communist China.

The visit came as the communist country wanted to improve relations with the West after the death of Chairman Mao Zedong.

The team played five exhibition matches, including one against the Chinese national team in Beijing in front a crowd of 90,000 people.

Alex Last spoke to West Brom legend, Brendon Batson, about his memories of the historic tour.
