A team of six raised more than £11,000 for a maternity bereavement suite at the Queen Elizabeth Hospital in King’s Lynn.
Friends Gareth Franklin, Lee Wright, Tommy Treacher, Jeremy Hargrave, Matthew Warfield and Steve Cousins braved torrential downpours as they cycled 100 miles.
Their route took them through West Norfolk, Wisbech and the South Holland district in Lincolnshire on May 8.
The £11,134 raised will go towards the appeal for The Butterfly Suite, set to open by the autumn.
It will provide a dedicated place for bereaved families who lose their babies either during, or shortly after birth.
The space will allow parents to create precious memories with their baby in a safe and welcoming space away from a clinical setting.
Mr Franklin, who organised the fundraiser, said: “Thank you so much for everyone that has donated so far for this amazing cause, we are all overwhelmed with how much we have raised.
“We hit the 100 miles in horrendous weather, but we were never going to give up. Please keep supporting.”
Caroline Shaw, hospital chief executive, said: “What Gareth and the team have achieved is remarkable and we are truly grateful to them for supporting our Maternity Bereavement Suite Appeal.
“Their donation will really make a difference to those families we care for who are going through their most difficult time. A huge thank you to them for their efforts.”
