Regiment Fitness is encouraging people to join the 3k Jingle Jog on Saturday, December 12, to raise money for the National Trust Charity.
The organisation wants the whole family to take part, dress up in a festive costume and get in the Christmas spirit from 11.30am at Dunstable Downs.
The team event will involve the members carrying a log round the route, the younger participants will be given mini logs.
Steve Nodwell, event organiser, said: “We want the whole family to take part, you can walk, jog or run the 3k.
“There will be lots of activities going on and children can meet Santa.
“It is £10 for adults and £5 for children, the money raised will go to the National Trust charity.
“We chose the national trust charity because it is a great location and that is where Regiment Fitness started.
“We thought it would be great for the youngsters to get involved and get active.”
There will be festive activities taking place throughout the day, a chance to meet Santa and prizes for the best costume and best dressed Father Christmas.
The National Trust Charity protects historic places and green spaces, for everyone to enjoy.
