The JCP Swansea Half Marathon, now in its fourth year, takes place on 25 June.

And this year Wales’ biggest summer half marathon will see a team of runners attempting to break a Guinness World Record.

The attempt led by Essex-born Paul Coker, a type 1 diabetic, is to break the record for the greatest number of diabetics to run a half marathon.

Paul, who started running in 2013 when training for a record-breaking summit of Kilimanjaro, is also spearheading a campaign to run 40 half marathons in 15 months in memory of Peter Baldwin, a 13-year-old boy from Cardiff, who died from undiagnosed type 1 diabetes.

Paul said: “I believe that having a positive attitude toward diabetes combined with the right nutrition and regular exercise have helped me manage my condition. The story of Peter deeply saddens me and my heart goes out to his family who will miss their son everyday. There are people who are living with diabetes without even realising it but knowing the signs are very important. I think that if this campaign can save just one life, my efforts at running 40 half marathons will be worthwhile.”

People who live with type 1 diabetes must inject insulin multiple times each day in order to keep blood glucose in the normal range and there are a number of signs for diagnosing diabetes, which are key to a quick response before complications begin.

David Martin-Jewell, director of Front Runner Events, said: “My wife and I have a son who is type 1 diabetic and know the challenges he faces on daily basis. What Paul is doing is inspiring to others particularly to those who suffer with this condition. He is demonstrating with his will and determination that anything is possible and that diabetes shouldn’t be barrier to living an active healthy life."

The JCP Swansea Half Marathon takes place along a flat course that is perfect for beginners and first-time half-marathon runners.

Although race entry has closed any T1 entrants who have already registered can join Paul in his attempt by becoming part of the team. For more info visit the Swansea Half Marathon website.
