Children at Campsbourne Primary School in Nightingale Lane, Hornsey, were encouraged to set daily goals and track the time they spent with a book in the read-a-thon organised by The Campsbourne Home and School Association (HSA) in February.
The children collectively read for 123,676 minutes, equivalent to 86 full days.
Altogether, they raised £4,600 for the HSA through sponsorships from family and community members.
Ten per cent of this will pay for new reading books for each class, with the rest going towards other educational activities.
Becky, mother of Emmett, the overall winner from the infant school said: “It’s definitely given Emmett’s reading a boost and he loved the whole experience.
“He was so motivated logging his time and seeing the numbers grow.”
Prizes were awarded to the children who read the most minutes in each class.
Acting headteacher Ms Currie said: “The dedication to reading and enthusiasm for raising funds for our school has been remarkable.
“Whether the children read a few pages or hundreds, every minute counts and their collective achievement is something to be celebrated.”
