Former England footballer John Barnes will greet 56,000 runners at mile 23 of the London Marathon, handing out Lucozade bottles, as the race aims to break the world record for finishers. Barnes, who has a long-standing partnership with Lucozade, expresses his excitement for the event and reflects on the increase in running participation, especially among women. After his marathon duties, he hopes to watch Liverpool secure the Premier League title, praising their consistency and comparing their current performance to his championship-winning team from 1988.
