Bishop's Stortford primary school Windhill21 is on the trail of the River Stort wildlife
Dip your toe in the Windhill21 summer trail challenge and explore the River Stort.
The Bishop's Stortford primary school's parent and teacher association (PTA) has set up a fundraiser for families to improve their physical fitness and mental wellbeing, and learn more about the flora and fauna of the waterway.
There are three route levels to try to complete during the summer holidays, each one with railway stations as start and finish points:
* Bronze – 4.6 miles (7.5km) from Bishop’s Stortford station to Sawbridgeworth station.
* Silver – 7 miles (11.2km) from Bishop’s Stortford to Harlow Mill.
* Gold – 8.7 miles (14km) from Bishop’s Stortford to Harlow Town.
Those who complete a leg can send a photo to email@example.com at the finish point on the river and the association will respond with a congratulatory certificate to print at home.
At the end of the summer, on September 6, three entries will be picked at random to win gift vouchers as prizes.
There is a fun 'River Stort Eye Spy' challenge for children to complete, too, testing their wildlife observation skills.
One of the organisers, Flora Klumpler, said: “As with all our challenges, there's an element of fundraising here. If you'd like to be sponsored to complete this challenge, please check out our crowdfunding page and ask your family and friends to sponsor you.
"This isn't compulsory, but if everybody was able to donate the cost of a cup of coffee or ice cream when they do the challenge, we'd be able to raise much-needed funds to help the school to replace the minibus.”
The association is reminding families to take care while close to the water and remember to carry a mask for the train back to Bishop’s Stortford.
