An 11 year old from Wellington has raised more than £1,000 to help support Dartmoor Zoo during the lockdown.
The site needs £11,500 a week to care for its 400 animals and Jack is using his daily hour of exercise to run sections of the challenge alongside his dad Alan.
Jack said: "I’ve been reading how the zoos in the UK are struggling due to the covid virus and I would like to help."
Dartmoor Zoo was made famous by the Hollywood film We Bought A Zoo starring Matt Damon and Scarlett Johansson which is based on its story.
A spokesperson for the zoo said: "Whilst we are temporarily closed due to Covid-19, our zoo keepers are caring for all of our 87 species of our 400+ animals, every single day, with the same love, care and dedication they deserve.
"No one knows how long this closure will last, and that poses a big challenge for us.
"This year more than ever, Dartmoor Zoo needs your support. Since closing our doors in March, the zoo has lost hundreds of thousands of pounds in critical funds.
"We have been heartened by the generosity of the public so far but along with others, we need more.
"Even after making considerable cuts, we still need to raise £45,000 a month to help us care for our animals and give them everything they need.
"Therefore, our weekly fundraising target is £11,500."
