Adventurers can take on Kent’s muddiest day out and raise money for charity by taking part in the annual KM Assault Course Challenge.

The event which is organised by the KM Charity Team and supported by London Fancy Box for the third year running is now open for entry.

Teams of six will conquer the course at Betteshanger Country Park (formerly known as Fowlmead Country Park) on Saturday, October 3 while collecting sponsor money for their favourite good causes. The newly extended course will be packed with more than 20 obstacles including tunnels, balance beams, rope walk, water jump and tyre wall.

Prizes will be awarded to the teams that raise the most money and create the best fancy dress outfits.

Event organiser Dominic Comins of the KM Charity Team said: “This is a great team building event suitable for most levels of fitness. It’s not timed so the emphasis is on having fun and encouraging your team mates to keep going.”

He added: “Last year’s event sold out quickly with 43 teams scrambling to raise £14,000 for good causes. This is a very popular event so don’t delay in reserving your place.”

Book a team at www.kmcharitychallenge.co.uk for £72 and use the online booking code KMACDL15 to receive a £12 discount. Participants must be aged 14 or over.
