An ultra-marathon runner who jogged up to 100 miles (160km) each day developed anaemia - because of his passion for long-distance running. The 41-year-old man, named as Christopher Pokrana, was told his 'repetitive forceful foot striking' was to blame for his condition. Following a health screening that spotted a form of mild anaemia, Mr Pokrana was worried and sought medical advice. Mr Pokrana told doctors that he would train for ultra-marathons on most days by running between 50 and 100 miles each day. They added that his intravascular haemolysis was most likely 'due to repetitive foot striking associated with his long-distance running'.
