Rugby League players past and present are saddling up to try and smash the world record for a static cycle ride.
Led by former Sheffield Eagles and Leeds Rhinos centre Keith Senior, the 25 strong-peleton aims to spend more than 30 hours on their bikes raising money for Rugby League Cares and the MND Association.
They have been inspired by the plight of his former Leeds teammate Rob Burrow, who's been diagnosed with Motor Neurone Disease.
Originally RL Cares had planned a fundraising ride in America, but that was postponed because of the global Covid-19 pandemic.
Calendar's John Shires spoke to Keith Senior and the former Castleford and Bradford Bulls hooker Wayne Godwin ahead of the world record attempt.
