Youngsters from every year group turned up for the special non-uniform day dressed in red and green elf outfits – and so did some members of staff and parents.
They all walked from school to the the promenade and back, for the biggest sponsored walk in the school calendar.
The event was staged a special tribute to Carole Jackson, who was the office manager at Chaucer for 24 years before her death from cancer in 2019, aged just 58.
The school, on Chaucer Road, has held several elf runs since, using the occasions to raise funds for Trinity Hospice, whose staff cared for Carol.
A previous event raised a magnificent £3,000 for the hospice.
Chaucer’s Andrea Logue, one of the organisers of the fundraiser, said: “It’s brilliant to see so many dressed as elves, it’s quite a sight!
"The children love it, and it’s a fun way of paying tribute to Carole and raising funds for a really good cause.”
Once all the sponsor money has been collected, it is planned that a member of the Trinity staff will be invited into school and presented with the cheque.
