A team of ten pals from a Slimming World group which meets in Wootton joined together to enter a team into the 2015 London Moonwalk.
The group are all members of the St James Doddridge Centre and Caroline Chisholm School group, run by Avril Spraggon.
They decided to do the walk last year and got into the swing by beginning training last October and slowly built up their distance until three weeks before the main event.
A spokesman for Slimming World said: “Following the healthy eating plan and by attending the group each week the ladies have not only lost weight but gained energy and the self confidence to enter into this Marathon walk.
“Along with the training the team have been busy fundraising with activities such as a race night sponsored and held at the Yeoman of England in Wootton, collecting tins and pin badges”.
The ten ladies marked up a combined weight loss of more than 22 stone during their training and also managed to raise more than £3,500 for breast cancer charities.
Emily Bibb, one of the team members, was celebrating not only her weight loss of nearly six stone, but also the fact that just a year ago walking down the street was a huge effort while 12 months later on she was completing her first marathon.
Gill Morgan was also celebrating on the night of her 50th birthday whilst remembering people she has lost recently.
The Moonwalk is managed by Walk the Walk who use funds raised to buy equipment and support for people with breast cancer continued research for a cure for the disease. Northampton General Hospital recently received two scalp coolers from WTW.
