The Pogi Challenge charity ride started with a non-timed 9.1km warm-up, before participants competed in the timed climb.
Mr Feather finished the race ahead of Pogačar with a time difference of around three minutes across the 45-minute race.
He said that it was “amazing to go up against” Pogačar, and added that it was “fantastic to be able to shake his hand at the end.”
Fund from the charity event go to the world champion’s own foundation, which contributes to various campaigns including helping seriously ill children and supporting emergency teams in disaster zones.
