Energetic pupils from Asquith Primary School in Morley raised cash for Cancer Rearach UK with a Race of Life challenge.
Key Stage Two youngsters ran a mile and children in the years below ran half a mile, whipping up £1,720.
Headteacher Gillian Austerfield said: “We actually did this before a couple of years ago, we always try to choose a charity to support. This year we chose Cancer Research.
“We’ve had a number of parents who have been affected by cancer in the last couple of years, so it’s quite apt.
“The parents have been particularly generous. We were really pleased with how all the children took part but also with how much parents gave in sponsorship.”
The Race for Life event took place in the Horsfall Street school grounds on July 1.
Every child who completed the challenge by either walking or running the route received a medal.
The youngsters also enjoyed a non-uniform day for the event, during which they also commemorated the 100th anniversary of the Battle of the Somme’s start.
People can fundraise for Cancer Research UK through a Just Giving web page, often in memory of family members who have been affected by cancer.
The charity works to fund new research into the causes, effects and treatment for cancer. For more information, visit http://raceforlife.cancerresearchuk.org
