Sharan Harris-Christensen, along with husband Christian, Dr Maelie Swanwick, and Barbara Kucharzewska, took 30 hours to complete the challenge earlier this month,
Inspired by the compassion and care of the hospice
Sharan, manager of Virtual Education Centre, RealTalk, explained more about why they signed up:
"We know how important Treetops is across Derbyshire and Nottinghamshire, providing end-of-life nursing care and counselling. We were all inspired by the compassion and care that the hospice delivers.
We were happy to do anything we could to support the charity. We're really pleased to have beaten our original fundraising target of £1,500."
The trek was a 'wonderful but challenging experience':
"We all walk a lot and we all trained. But nothing quite prepares you for the intensity of walking three back-to-back marathons over three days!
A wonderful, shared experience
"It was great for team building. We all had times with aches and blisters when we needed each other to take over being the pacemaker, and motivating each other. It was a wonderful, shared experience.
The trek took in the beautiful countryside and views from Beacon Hill and Bradgate Park. The team were met with applause at the finishing line at the National Memorial Arboretum.
"We are already planning to enter again next year with a bigger team. We plan to break it down into stages to encourage more people to join as a relay."
The money raised by the team will help fund nursing care for patients at the very end of life across Derbyshire and Nottinghamshire.
