A sponsored walk is taking place around the Lynnsport running track for 13 hours to raise money for the Red Wellies on Sunday.
The walk is taking place on Sunday from 8am to 9pm.
There are 15 teenagers from around Lynn taking part, hoping to raise £500 or more for the brain tumour charity and aiming to walk 120 laps, which in total accounts to the distance of a marathon, if not a little more.
Red Wellies is a charity which raises money for the research of Glioblastoma Multiforme (GBM), more commonly known as brain tumours.
Red Wellies help fund new treatments that help prolong the life of sufferers and will help spread the use of a cure when it is eventually found.
The charity was created after the death of Lisa Wiles.
The event is happening as part of the youngsters NCS Social Action Project, which is run by the College of West Anglia.
NCS (National Citizen Service) is an opportunity for all year 11 and 12 students all over the country to develop skills for work and life and to make a difference in their society.
The Social Action Project is the part of NCS where the teens choose to support a local cause and help raise awareness, money and support for the cause, in this case Red Wellies.

To achieve the aims of the walk the participants will need all the support they can get and the public can do this by sponsoring the participants if you know them, by coming along to Lynnsport throughout the day to cheer them on or by donating to the charity directly through their website.
All and any support is welcomed and gladly appreciated.
In addition to the sponsored walk, nine students gave up their time to spend a day at Matalan in Lynn last Sunday, alongside Red Wellies to help raise a total of £83.83 from the generosity of the public.
