Irish triathlete Bryan Keane completed a remarkable return from a career-threatening injury to finish in the top 40 at the Olympic triathlon at Rio 2016.

Keane's dreams of competing at the London 2012 game were cruelly ended and his athletic future left in serious question after a collision between his bicycle and a car left him with a shattered kneecap in 2010.

However, years of rehabilitation and an unquenchable desire to become an Olympian finally paid off today as he finished 40th in the men's triathlon.

Alistair Brownlee became the first triathlete to retain the Olympic title as he led brother Jonny to a family gold and silver, with Henri Schoeman taking bronze for South Africa. 

Keane brilliantly embodied the spirit of the Olympics and, as the oldest competitor in the field at 35, finished in a time of 1:52:09 for 40th place.

 At the top of the field, the Brownlee brothers - who finished first and third in London - did not put a foot wrong in front of packed crowds on Copacabana.

It came down to a race between them, and Alistair made his break on the third lap of the run, pulling away to claim a dominant victory

Jonny comfortably held on for silver, making the brothers the first to finish one and two at an Olympics since Italians Piero and Raimondo D'Inzeo of Italy in equestrian in 1960.

Alistair sauntered down the finishing straight, at one point stopping and holding his arms aloft before crossing the line in a time of 1:45:01.

The final gap to Jonny was six seconds, with Schoeman +0:42 back in third.
