[7] Fields says that he was inspired to visit the North Pole after watching a breakfast television article about Ben Fogle and James Cracknell looking for a third member to assist in their expedition of Antarctica.

Though he was too late to apply, his enthusiasm for the project was noted and he was asked to recreate the 1908–1909 expedition by Robert Peary and Matthew Henson, which reached what was believed at the time to be the Geographic North Pole.

On his Countryfile appearance, he said that he believed that some Black British people do not regard the countryside as "somewhere that's for them" and undertook his North Pole expedition to show that things are not necessarily impossible to achieve.

[7][9] He co-founded the WeTwo Foundation, which provides adventure opportunities for underprivileged young people; their inaugural trip to Antarctica was in November 2022.

[10] On Tuesday the 23rd July 2024, Fields was made Honorary Colonel and corps ambassador to HM Royal Marines alongside Olympian Victoria Pendleton.
