Warburtons will donate £300,000 across three years to facilitate the expansion of Junior Parkrun, the series of 2km running, jogging and walking events for participants aged four to 14.
Parkrun currently organises 81 of these events throughout the country. Warburtons hopes its partnership will see this number expand by 72, and engage more than 60,000 young people and their families.
The first events will focus on engaging disadvantaged communities and educating them on the benefits of physical activity.
Brett Warburton, executive director at Warburtons, said: "As a family-owned business, family is at the heart of everything we do. We believe we have a responsibility to play an active role in our communities and do so through our community investment programme, Families Matter.
"We are committed to supporting young families build healthy lifestyles through a balanced diet and exercise. We are delighted to partner with parkrun to help more families take part in physical activity which is fun for all the family."
He added that the partnership complements its School Visitors programme, which helps 30,000 children a year learn about the importance of healthy eating.
