International showjumper Will Whitaker, equestrian YouTuber This Esme and Olympic dressage rider Charlotte Dujardin are supporting Brooke’s MyHackathon challenge, which returns this month for the fourth year.

The challenge, which runs from March to October, calls upon riders across the UK and beyond to get out and hack 100 miles in 100 days and raise £100 for Brooke.

Will said: “I’m really excited to be supporting this year’s MyHackathon and helping to make a difference to the lives of vulnerable horses, donkeys and mules around the world. It’s really easy to sign up, so you can start clocking up the miles straight away. Jimmy and I love to take advance of the beautiful hills here in Yorkshire and it helps him to stay fit while I get some fresh air and clear my mind.”

There’s no registration fee and riders can sign up simply by visiting Brooke’s website and then setting up a JustGiving fundraising page. All participants who complete the challenge and raise £100 will receive a certificate and pin badge, with additional incentives for those who raise over £250.

Brooke Ambassador This Esme took on the challenge last year and shared her journey with her viewers. This year she’s urging even more of them to get involved. She said: “I’m so excited to be supporting MyHackathon this year. Casper and I had a great time taking part last year and it was brilliant to know that we were helping less fortunate horses, donkeys and mules around the world. I visited Brooke’s work in Senegal last year and saw first-hand the amazing difference that donations can make. It’s really easy to sign up, so start building up those miles!”

Brooke’s Global Ambassador Charlotte Dujardin is also showing her support for the challenge once again this year. She said: “I’m thrilled to be continuing my support for Brooke’s MyHackathon this year. It’s a great way of keeping fit and spending time with your horse whilst also making a difference to the lives of working equines who need our help most.”

Riders can join Brooke’s official MyHackathon Facebook group to share their tips and progress with hundreds of other hackers across the country. Each month, Brooke will select a Hacker of the Month from the group and award prizes including a branded tote bag, tabard and body warmer.

This year also sees the return of My Mini Hackathon, which gives small children or ponies the opportunity to take part by completing 10 miles in 100 days and raising £100.

All money raised from the challenge will go towards Brooke’s work across Africa, Asia, the Middle East and Latin America, bringing lasting change to the lives of working animals. For every £100 raised, Brooke could provide a community with a permanent water trough for its animals, train two farriers to trim and balance hooves properly, or support women’s groups that give female owners the skills that will benefit them and their animals for life.
