In a challenge which has been named '1000 km against leukaemia', on Sunday 26 November Iván González will begin a 1,000 kilometre duathlon. The long-distance runner, who has leukaemia himself, will run 600 kilometres and cycle 400 kilometres to pay homage to Pablo Ráez.
González will start in his hometown of Aviléz and end in Marbella, where Ráez grew up. His challenge will raise money for the Fundación Josep Carreras, a foundation which fights leukaemia, as well as hoping to raise awareness about the importance of donating bone marrow.
Around one thousand runners are expected to join Iván for the first stretch of his run. During the eight stages of his journey he will go through 10 provinces, six communities, and 88 cities, including Segovia, Madrid, Toledo, Antequera and Marbella. It is predicted that he will arrive at the finish line on Sunday 3 December, around 5.30 pm.
