BBC Sport advent calendar - 11 December

Time for one of the year's most unlikely heroes on day 11 of BBC Sport's 2012 advent calendar.

Niger rower Hammadou Djibo Issaka wins the hearts of GB rowing fans at Eton Dorney as he struggled to the finishing line in the men's single sculls at the Olympic regatta.

Issaka, who had only taken up the sport three months before the Games, eventually crossed the line, to massive applause, a full minute and 39 seconds after Lithuanian winner Mindaugs Griskonis.
