A dad reckons he's the first person to have run London’s entire transport network - covering almost 500 miles in four months. <br /><br />Dave Thomas, 64, covered the 12 Tube lines, six Overground lines, the tramlines, the Docklands Light Railway - and a cable car.<br /><br />Having taken a selfie at each station for evidence, the retired NHS worker is now hoping to hear back from Guinness World Records about whether his achievement is record-worthy.<br /><br />But he says he's been in touch with Transport for London (TfL) who believe his efforts are "unique".<br /><br />The dad-of-two has raised nearly £6,000 by taking on the challenge, which will be donated to the Chance for Children charity.<br /><br />Donate here: https://www.justgiving.com/crowdfunding/dave-thomas-2-tflchallenge-japan.
