Man v Horse race: Hundreds try to beat horse in race over 22 miles
BBC Sport Wales visits the annual Man versus Horse race in Llanwrtyd Wells in mid Wales as 650 runners try to beat a horse over a 22-mile course.
The race has been held since 1980, after founder Gordon Green argued in the local pub that a runner could beat a horse over a long distance.
In the previous 39 years, only two runners had beaten the fastest horse - the last occasion being in 2007.
