A man whose older sister suffered from type one diabetes for almost 20 years is training to run the London Marathon to fundraise in her honour.

Joe Staggs, 25, a property accountant from Epping, was inspired to take on the 26-mile Virgin Money London Marathon after seeing first-hand the effects living with diabetes can take.

He said: “After learning a huge amount from the group my parents then became volunteers, helping fund raise, and supporting the group where they could in order to allow new members to gain knowledge.

“I became wise to things to look out for to make sure my sister was looking after herself, nagging her to test her blood, guessing what her sugar levels would be and asking if she had taken her injection. I'm sure I became very annoying for her.”

Diabetes is a condition where there is too much glucose in the blood because the body cannot use it properly.

If not managed well, both type one and type two diabetes can lead to devastating complications, including sight loss, amputation, kidney failure and stroke.

With the right treatment and support people living with diabetes can lead a long and healthy life.

The 25-year-old is aiming to complete the marathon in around five hours and has been training by running in all weather conditions, most recently hail and sleet.

He said: “Some days you feel like someone has swapped your running trainers for a pair of concrete boots, others you can be running and not even realise how far you’ve gone.”

The marathon hopeful is aiming to raise £2,000 for Diabetes UK and is planning a number of fundraising activities including a quiz night.

Peter Shorrick, Diabetes UK Midlands and East Regional head, said: “Our much-needed work wouldn’t be possible without the determination and generosity of our incredible fundraisers.

“We are extremely grateful to Joe for his hard work – running a marathon is no mean feat.

“The money raised will help fund ground-breaking research, care services and campaigns that can change the lives of those living with diabetes.”

The Virgin London Marathon will take place on Sunday, April 26.
