He is the public face of a double glazing company and this summer Jeff Brown is prepared to go through the 'pane' barrier to raise £10,000 for the Jane Tomlinson Appeal.
Jeff - famed for his buy one get one free offer in Safestyle Windows adverts - is also often the matchday host in the corporate lounge at Turf Moor, the home of his beloved Burnley FC.
And when Premier Range, the club's sponsor, threw down the gauntlet by offering to sponsor Jeff £10,000 to complete the new Jane Tomlinson Pennine Lancashire 10K, he immediately took up the challenge.
With the help of personal trainer Jamie Kennedy, Jeff has shed almost four stone in less than three months and is on target to complete the 10k in Burnley on Sunday, 2nd June.
Jeff, who lives in Burnley, said: "Premier Range doubted I would ever be able to do it, but I'm determined to finish it and get that £10,000 from them for Jane's charity.
"I had my last sausage and egg butty on January 2 and I've cut
out all bread and potatoes since. I've restricted what I have been
drinking and I've been
training three times a week, walking and on the cross trainer. The weight has been falling off and I feel so much better.
"I'm actually really enjoying the exercise. It's become a way of life, like food used to be for me. I'm the sort of person who wouldn't have one bag of crisps, I'd want 15! But now at least I'm doing something that's good for me.
"I'm really looking forward to race day - and I never thought I'd say that!"
Trainer Jamie, of Fitness Experience (FX), who is providing his services free, said: "Jeff is doing fantastically well. There is still a long way to go with his training but I am confident he will make it."
Burnley FC's manager Sean Dyche said: "Jeff is taking on a tough challenge for a great cause. He's obviously putting in a lot of effort and I wish him all the best in his target to cross the finish line - I'm sure he'll make it."
Siobhan Curtis, Jane Tomlinson Appeal legacy manager, said: "We are really grateful to Premier Range for offering such generous sponsorship and to Jeff for taking on the challenge.
"We hope the effort and determination he is displaying inspires others to put on their running shoes and sign up for the Pennine Lancashire 10K It is a wonderful event and promises to be a really enjoyable day."
Premier Range General Manger Martin Mensforth said: "We had a little banter at a recent game and as a result we have thrown down a challenge to Jeff to get fit and join in.
"We have committed to donating a pound for every metre Jeff runs - so 10,000m equals £10,000.
"As the race is coming to Burnley for the first time it seemed too good an opportunity to miss."
Burnley Football Club is also supporting the Jane Tomlinson Appeal by inviting fans to support Jeff through a special 'Just Giving' page. The club will also chronicle Jeff's training through their Clarets Player channel and give fans unparalleled access to his gruelling training regime ahead of the 10K run.
The Asda Foundation Pennine Lancashire 10K,
organised by Jane Tomlinson Run For All, starts and finishes at the Mechanics Theatre in Manchester Road and takes in some of the town's best-loved landmarks including Rowley Lake, Towneley Hall, Thompson Park and Turf Moor Stadium.
