The firm’s 11 runners set a target of raising £1,000 for Birmingham Women’s Hospital as they took part in the city’s 10k run on Sunday.
Currently the team has raised £2,103, 210% of that figure, thanks to the generosity of more than 140 supporters.
Another colleague also had his own page so the total was boosted to more than £3,000.
The runners’ JustGiving page explained why they chose to support the hospital.
It says: “AFH's chosen charity for 2018 is in memory of the wonderful Amy Shimell, who's two younger sisters are employees here at AFH.
“Amy worked at Birmingham Women's Hospital as a nursery nurse on transitional care and the neo-natal unit, she was incredibly passionate about what she did and loved caring for all the babies and family's in her care.
“Birmingham Women's Hospital is also where a lot of our staff have welcomed children and grandchildren into the world.
“It is the closest women's hospital to our head office therefore supporting this charity only ensures a better future for us all.”
AFH’s charity co-ordinator, Jenny Read, who was one of the runners, said: “It was an amazing experience. Despite it being the hottest day of the year - and a few tired muscles! - it was totally worth it.
"We never imagined we’d beat our target three times over.
"It’s a wonderful demonstration of the affection everyone feels for BWH and a great tribute to Amy’s memory.”
