A veteran runner will be joined by his son as he looks to complete his seventh and final marathon.

Alan Segall, 50, and his son Gabriel, 18, of Borehamwood, will run the Brighton Marathon on Sunday, April 12, in aid of Parkinson’s UK.

The duo will be running in honour of Mr Segall’s mother and Gabriel’s grandmother, who lived with Parkinson’s disease for 24 years and died last year.

Mr Segall said: “My main motivation was to do it for my mum, Norma, and to raise money to help find a cure for Parkinson’s. I’ve run marathons before but this is the first I’ve done one since she passed away, so it means a lot.”

Having been unlucky with the London Marathon ballot, the father and son will take to the streets and seafront of Brighton to run their 26 miles.

While Mr Segall has run his fair share of marathons before, this will be his son’s first attempt. Gabriel has been building up to it by completing five half marathons, including last year’s Watford Half Marathon in which he raised more than £900 for Parkinson’s UK.

Mr Segall said: “It was my son who inspired me to get back into running after I stopped for several years. I’ve been running for a long time but my legs will give in at some point. We’re training together but now I’m trying to keep up with him.

“If either of us struggle in the marathon, we’ll wait for each other so we cross the finish line together.”

With the marathon only two weeks away, the pair are staying healthy with plenty of rest, food and moderate training.

Although supporters at the marathon hand out drinks, energy bars and sweets to help the runners, Mr Segall added: “I think the main thing that will get us round the course is people cheering us on. It’s a wonderful feeling. I’m getting excited for it.

“But I’m also really looking forward to finishing the race – for good this time.”

They hope to raise £1,000 for Parkinson’s UK and have raised nearly £300 so far. To make a donation, visit www.justgiving.com/gabealbrm2015
