Fun-seeking families are being urged to sign up quick for a charity challenge which promises messy madness.

The NSPCC’s brand new Messathon fundraiser will take place at scenic Blaise Castle Estate on Saturday, July 29 – and would-be Messathletes have only a month to register.

Participants will splatter through mud, swoosh along water slides and scramble over hay bales during the exhilarating 2.5km obstacle course – all for a good cause as they help the children’s charity fight for every childhood.

Families with children aged 4 and above will also take on a ball pit, cargo net, wall climb and more.

Once mums, dads and kids finish the course, they can then make a day of it by visiting the event village and enjoy a variety of attractions on offer, including food stalls, games and entertainment.

Cash raised through entry fees and sponsorship go to the NSPCC, and every participant will receive a free Messathon t-shirt.

Anna Keir, NSPCC Community Fundraising Manager for Bristol, said: “We are counting down the days to Messathon at Blaise Castle Estate, and it looks set to be the perfect event for bringing families together, getting them active, working as a team and of course, getting messy!

“We would urge interested families to sign up quick to avoid disappointment. Entries must close on the night of July 23. We wish all participants good luck in their fundraising and would like to thank them in advance for helping the charity support and protect children from abuse.”

This is the second in a series of three NSPCC Messathons, new for 2017, following last month’s event in Surrey and next month’s in Hertfordshire.
