A mum has contacted Guinness World Records after her five-year-old son beat his own 'world record'.
Jack Unsworth, five, from Fazakerley, ran 5km in a time of 23 minutes and four seconds at Croxteth Park parkrun on Saturday (January 28). Two weeks before that, Jack recorded a time of 23:58, which led his mum Vicky Unsworth to think he set a new world record for his age.
In 2014, Runner's World magazine reported that a five-year-old in Duluth, Georgia, ran 5km in 24:08, setting a single-age world record. Jack has now run the distance more than a minute faster than that, so Vicky believes there is every chance he is the fastest five-year-old on the planet.
