A team from Solihull’s Saint Martin’s School is preparing to cross the distance of Lake Malawi on bike.
Katrina Davey-Reid will be joined by four of her classmates and teacher Tracy Gallagher in the challenge.
It will see them attempt to complete a distance of 75 kilometres on exercise bikes at Tudor Grange Leisure Centre on Saturday, June 28.
All the money raised will go to fund Katrina’s placement as a teaching assistant and sports coach in Malawi in September.
A talented netball player, the 18-year-old played for Leamington Ladies in National Premier Division 3 and notched up more than 750 hours as an umpire and volunteer coach for junior clubs.
Now she is looking forward to sharing her skills with youngsters in one of the world’s poorest countries.
Her proud mum Alice said: “I think she’s done an amazing job, balancing all her work in her A2 year with her ambition to volunteer. She has been coaching netball at school but this will be a very different experience for her.
“There could be up to 60 youngsters in a class, and some won’t even have shoes.
“But netball is popular in Malawi.
“It’s ranked the fifth best in the world for netball so there will be a lot of positivity.”
Since launching her appeal last November, Katrina has raised two-thirds of the £3,000 needed for her trip.
