Students and staff from David Ross Education Trust schools either ran or walked a course within their bubbles earlier this month before the end of term.
The money will go towards the trust’s Inspiration Fund, which supports enrichment programmes and activities, such as sports clubs, music festivals and instrument lessons.
In a display of solidarity, almost every school in the trust took part, and over 2,000 students raised an astonishing £50,000.
Trust chief executive Stuart Burns said: “I am delighted that so many of our pupils signed up for the Santa Run and we are so proud of their efforts.
"We are extremely grateful to all of our students and families for supporting this event so generously, especially at the tail end of an extremely challenging year.
“The money raised will be invaluable in funding enrichment programmes across the trust. At DRET we are focused on providing a world-class education that broadens our pupils’ horizons.
"Our enrichment programme is second to none in the state sector, providing wonderful opportunities for pupils to explore new things, develop their passions and discover their talents.
"The run is a fantastic way to support this work, and a fabulously festive way to mark the end of term!”
