Nadine Rieder looks tanned and in great shape when we meet in her home village of Winkel in Allgäu, Germany. She only returned yesterday from a two-week training camp on the island of Majorca. There she spent some 60 hours on her bike, covering around 1500 km. 26-year-old Nadine Rieder is one of the fastest women on a mountain bike and counts four German championship titles among her many successes. The Allgäu-born athlete is aiming to qualify for the cross-country discipline at this summer's Olympics in Rio de Janeiro. Only two German women can qualify for this event, so the competition is tough and the training intense. In addition to countless hours in the saddle, Nadine keeps fit by swimming, jogging, cross-country skiing and working out. Her workout can be performed almost anywhere – at training camp, during vacation, or in a hotel room when Nadine jets from race to race. The exercises don't require equipment or a personal trainer - just a yoga mat and comfortable clothing.
