Student midwives have pledged to walk 23 miles after they finish exams to raise money for mothers in crisis and bereaved families.

The group of second year midwifery students, from Kings College London, are walking just short of a marathon distance on June 21.

They will start the walk at 8am and hope to finish by 6pm, the group say this is the equivalent of a “long day’s work” at the hospital.

The group hope to raise £10,000, which will be split between their three chosen charities, Remember My Baby, Jada’s Room and Islamic Help’s Birth Campaign.

Jada’s Room is a charity particularly important to student midwife Lauren Petrie, from West Kensington.

The charity was set up in memory of her still-born daughter, Jada, who sadly died four years ago. A bereavement suite was set up at Queen Charlotte’s and Chelsea Hospital. It offers a “quiet, calm environment” for parents and families that have recently lost a baby.

The 37-year-old is involved with public speaking on the topic of stillbirth, giving talks about her experience and the impact on her life.

She said: “With other talks I have heard on stillbirth, I thought it has a really negative feeling around it, but mine is only positive. It was one of the most harrowing and awful things that have happened to me, but I have to think of the positive side for Jada.”

The idea of raising more money for the charity came up after a talk to her year group. Other students had their own charity involvements, so they have decided to donate to all three.

Remember My Baby offers free remembrance photography for babies lost before, during, or shortly after birth. Islamic Help’s Birth Campaign helps provide pregnant Syrian refugees living in Jordan with safe healthcare, sanitary items, food and clothes.

Money donated to Jada’s Room will go towards the cost of maintenance, as well as to funeral costs and an annual remembrance service for families.

Nearly 50 student midwives will be walking the route, which will take them past each of the seven maternity wards they work in. They will start the walk at Princess Royal University Hospital in Orpington and move on to Lewisham Hospital, King's College Hospital in Southwark, St Thomas' Hospital in Lambeth, St Mary's Hospital in Paddington and Chelsea and Westminster Hospital.

The group will finish at Queen Charlotte's and Chelsea Hospital in White City, the hospital with Jada’s Room.

Lauren says they will keep supporters up to date with their progress via Twitter, and that they will have a 20 minute rest at each hospital stop.
