Batman and Robin are hoping to become charity champions by completing a challenge to hit 5,000 golf balls a minimum of 450,000 yards in three and a half hours.
The superheroes, aka golfing buddies Gary East and Steven Coxon, from Spalding, will be donning their masks and capes and giving the challenge a shot at Boston West Golf Club in aid of Children in Need.
Gary said: “We are both in our early 30s with young families.
“Children in Need is a charity we both hold close to our hearts.
“While many of the stories are emotional, they inspire you to want to participate towards a great cause, hence our challenge to be involved and help.”
So far the pair have been sponsored almost £300, but are hoping more pledges of money will be made to support the good cause.

The pair will also be collecting at Baytree Nurseries Garden Centre, Weston, on Saturday, to boost their total.
