Huw Lobb was the first runner to triumph over horse three years ago

Another man also beat the first horse home in the race held every June at Llanwrtyd Wells in Powys.

German participant Florian Holginger came in 11 minutes before the first horse while John Parkinson from the UK was a minute behind the winner.

Organisers said Saturday's hot weather meant many of the 45 horses taking part were withdrawn from the marathon.

The 22-mile race now in its 28th years attracts competitors from all over the world and this year a total of 250 runners took part.

Throughout the race the runners try to out run the horses over marsh, mountain and bog.

Around 250 competitors and 45 horses took part this year

Organiser Gareth Davies said the paramount concern this year had been for the safety of the horses taking part.

"Forty five horses started the race but there were regular checks and vets were stopping those which got too tired," said Mr Davies.

The first man home on Saturday completed the course in two hours and 20 minutes.

In 2004 a London marathon runner became the first human to triumph in the annual dual with horse and scooped a £25,000 prize.

This year's winner will take home a £3,000 prize.
