Marathon man on course to beat personal record

An Irish ultra runner who is the only man on the planet to run seven marathons in less than seven days on seven continents, is expected to break his own record today.

Richard Donovan is on course to complete his final run in Sydney and smash the five-day barrier.

Mr Donovan, a 45-year-old father-of-one, began his epic journey in the extremes of Antarctica, running the first 26-mile leg in -20ºc at the Russian Novo science base last Wednesday.
