Jordan Rolfe, 30, from Holton St Mary, raised more than £2,500 for Great Ormond Street Hospital through an Ultra White Collar Boxing (UWCB) event at Trinity Park in Ipswich.
Inspired by his children and motivated to reclaim his health after the pandemic, Mr Rolfe decided to take on the challenge not just for himself, but for families facing far greater battles.
Mr Rolfe said: “Since the pandemic I had allowed myself to lose control over my health; I became lazy and overweight.
“Even small things like playing in the park together were a challenge.
