Adie Doe, 49, is taking part in the Cambridge Half Marathon and says: “Six months ago, I couldn’t even run a mile, now I am up to 11 miles relatively easily. The progress has been good to see!

"I’m not a runner so it's the first time I’ve done anything like this. It’s quite a challenge!

Adie’s sister Lynn Charles, 47, had kidney failure at the age of 21. Their mum donated a kidney 23 years ago, but organs have a limited life span and it only lasted for 22 years.

Adie, of Bury St Edmunds, said: “It meant Lynn needed another transplant operation. Unfortunately, there is a time scale on organ donation, which a lot of people don’t realise.

“In January 2019 I went into the organ pool scheme where you agree to donate in lieu of a family member. There were six people involved in three different hospitals up and down the country, at the same time having the operation and it all went well.

“Lynn made a really good recovery and within eight months she had completed a charity walk of 11.5 miles. Not to be outdone I agreed to do the Cambridge Half!”

Three million people in the UK have kidney disease, yet one million of these don’t know they have it. There is no cure, and for people with kidney failure the only way to stay alive is dialysis or transplant.
