Fifteen years after the death of three-times F1 world champion Ayrton Senna at Imola, we talk to fellow Brazilian F1 driver Alex Ribeiro about his memories of Senna.  

Listen to find out who won when Alex and Ayrton took part in a celebrity go-kart race!  Alex also tells about about Senna's interests off the track and his legacy today, the Foundation that he set up before his death to help deprived children in Brazil.

Imagine training for four years to compete in the Olympics with your heart set on winning the gold?  You perform well, only to come second.  Not once but twice, in successive Olympics.  Would you consider that as success or failure?  We ask one athlete who experienced just that, Kenyan marathon runner Catherine Ndereba, who won silver at the last two Olympics in Athens and Beijing.
