Mike Lawlor admits he will not be short on motivation when he takes part in the London Marathon for the first time on Sunday.
The Horncastle based civil engineer, 32, says his beloved nan will be on his mind every step of the way.
She died a couple of years ago from ovarian cancer.
Mike is running the marathon to raise funds for ‘Ovarian’ - a charity group which supports families affected by the illness.
Mike said: “My nan was a special person. We all miss her.
“My mum has done some fundraising over the last couple of years but I’ve always wanted to do something myself.
“It’s a cause that is really close to us.
“When I’ve been out running in the bad weather this winter, my nan has been the motivation to carry on.
“Hopefully, that will prove to be the case on Sunday. I want to do it for her.”
It is Mike’s first crack at a marathon and he is aware he could have chosen an easier way to see the famous London sights.
He explained: “I applied for a place and was lucky enough to get in at the first time of asking.
“When the confirmation came through, I thought I’d better start training.
“I’ve done a lot of running. I’ve lost weight and feel a lot better, but the real test will come on Sunday.
“It’s 26 miles. The best I’ve managed so far is 20 although they advise you not to push yourself too much in training.”
Mike admits he’s looking forward to the challenge and hopes to complete the course in a very respectable 3 hours and 30 minutes.
So far, he’s raised £700 in but hopes to top £2,000 with the marathon and a charity golf day held at Louth Golf Club last Sunday.
He added: “It would be great to get to £2,000 and hopefully that would help make a difference.”
