FIREFIGHTERS from Skelmanthorpe were starting their bid to break a world record today.
The part-timers aim to break the 24-hour ladder-climbing record, which now stands at 65 miles.
And they are making the attempt outside Wakefield Cathedral starting at 3pm today and ending at 3pm tomorrow.
The event will raise money for the Make-A-Wish Foundation UK, a charity which grants wishes to children living with life-threatening illnesses.
The 10-strong team of firefighters has been training hard for a year.
A ladder structure has been built at their station and they have been running and rowing too to make sure they are in tip-top condition.
But it will be tough going.
Each team member will spend 30 minutes climbing the ladder with a 20 minute rest period.
This pattern will be repeated nonstop for 24 hours.
Watch Manager Richard Meakin said: "We have been training very hard and are feeling confident. Now all we need is good weather.
"Rain could be a problem as it will make the poles we slide down after each climb slippery."
