Des Keenan, who turns 70 later this month, will be covering over 40 miles and visiting 20 towns including Londonderry, Ballymena, Armagh and Dungannon as part of the challenge.He is hoping to raise £70,000 for two local charities - Action MS and Saint Vincent De Paul.Mr Keenan said: "I wanted to do something special for two charities that are close to my heart and I thought I'm fit to do it so why not do something different?"There's bed pushes, pram pushes, we thought we'd do a cooker push."Mr Keenan was at Stormont on Monday with his custom-made, Waterford Stanley Cooker to get the support of local politicians.He's setting off from Cookstown next week to begin his five-day journey."It's difficult to push this cooker up and down the main roads so I've been hill-waking up and down the side of mountains for this and hopefully that will keep me in good stead," he added."It's 280 kilos so it's quite heavy, but we'll get there."
