James Heptonstall and Noel Carroll – who millions watched in their Race The Tube challenge on YouTube last year – have expanded their team for a new race.
The stunt has been uploaded onto their Epic Challenges YouTube channel and shows the four athletes race 553m from Island Gardens to Mudchute station in just one minute.
The friends have also uploaded their failed attempt to race the DLR between Cutty Sark and Mudchute, running through the Greenwich Foot Tunnel.
Following the successful challenge on June 26, Mr Heptonsall told the Evening Standard: “We have plans for another one but it is top secret. It should be quite exciting.”
