While many people might take part in marathons and run against the clock, you don't often see them competing against an animal with four legs for the winning position.

The Man vs Horse Marathon, held in June, is a 22-mile race that starts in the town square of Llanwrtyd Wells and that takes in some of the finest scenery in mid-Wales.

It began in 1980 as an event to attract tourists. Today, hundreds of runners and horse riders from across the world tackle the hilly course which covers varied terrain - from farm tracks and footpaths to forestry roads and open moorland - with a total ascent of 3,000ft.

Individuals, or teams of three, can take on the horses for a fee of around £22 or £60 respectively. It took 25 years before a man finally beat a horse; Huw Lobb won in two hours, five minutes, beating the fastest horse by two minutes.
