Schoolchildren and Lincolnshire Co-operative staff are undertaking a 200-mile charity cycle today, at the Tritton Road store, in Lincoln.
Pupils from Brantson Community Academy alongside Lincolnshire Co-op staff are attempting to cycle the distance from Lincoln to Brighton on exercise bikes, raising money for Plan UK, Pascal and ChildLine.
Two of the charities are the Lincolnshire Co-op's charities of the year and ChildLine was chosen by Branston Community Academy.
The cycle relay involves around 30 Lincolnshire Co-op staff and teams of staff and students from the school.
Participants will cycle in 20 minute slots and the group is hoping to complete the challenge in five hours, racking up miles on two bikes between 10am and 3pm.
Alison Hackett, Healthy Schools Coordinator from Branston Community Academy said: "We are a Healthy School and came up with the idea of doing a sponsored cycle ride for ChildLine as it is their 25th anniversary this week."
Aimee Kendall, 16, the school said: "I thought it was good to raise money for the ChildLine because it is based around people our age, so people we could know as well as others around the country."
Pupil, Corinna Kent, 16, said: "I could have a friend who needs help but is too scared to talk so I might not realise it but I'm helping by being here today."
LA Fitness, in Lincoln, provided the two bikes and are supporting the day.
