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.
Doctors explained how the constant barrage of abuse on his feet against pavements led to haemolysis – the destruction of red blood cells.
And this then led to mild anemia because of the rapid obliteration of his blood cells, according to a medical case report.
