Tyson Fury has challenged Anthony Joshua to a 2000m rowing race for charity.

The former heavyweight champion uploaded a video to Instagram where he proposed the idea of the race, whilst his trainer Ben Davison suggested they partake for Sport Relief.

In the video, Fury made several bold claims, including a belief that he was a “better athlete” than Joshua.

The 29-year-old has been out of the ring since his 2015 victory against Ukraine’s Wladimir Klitschko, where he became the lineal heavyweight champion.

Several rumoured comebacks in the time since then have proved empty, but Fury’s current fitness drive seems to be heading in the right direction.

A potential battle in the ring with Antony Joshua may well be on the cards one day, but the Watford fighter will first have to navigate bouts against Joseph Parker, and then potentially Deontay Wilder in what would be a unification bout.

If Joshua and Fury were to meet, it would likely take place next year.
