Perfect Finnish helped

Periods of intense training for two African athletes at a Finnish javelin school have overturned the natural world order in the physically demanding and technically challenging event.

There was a shock at Wednesday's world championships when Kenya's Julius Yego won gold with the third longest throw of all time.

In all world championships since 1983, there has only been one non-European gold medalist, South African Marius Corbett in Athens in 1997. Otherwise, medals have remained largely the preserve of European countries.
