This week on the Fired Up Sport Podcast, in association with Sport England and This Girl Can, the eyes of the sporting world will be on the World Athletics Championships in the Qatari capital Doha but one of the major stars will be absent. Caster Semenya, the 800 metre World and Olympic Champion will not race, after new rules on testosterone levels in female athletes meant that she would have had to take drugs to reduce that hormone if she wanted to compete. Semenya refused. Clare and Kirsten hear from Olympic Channel journalist Evelyn Watta who says it's not only the Olympic Champion who feels abandoned by the system. She's been speaking to female runners from Kenya who have been dropped from the team and left without any support. They are angry but mainly confused. And ahead of the Russian Grand Prix, they speak to British racing driver Katherine Legge about her ambitions to race in Formula One and why she is determined to spread the word that motor racing is a career for women.
