Rob Greenslade, (44), who lives in Barnstaple, signed up to the 13-mile challenge as part of his recovery journey following some mental health struggles.
Rob explained: “I started running to be a healthier, happier version of myself. I was quite out of shape and my mental health had been suffering. I began running and needed some sort of target to train towards.
“After deciding to sign up to the Royal Parks Half Marathon, it seemed fitting to also use the challenge to raise money for a good cause at the same time.”
Rob lives with his wife, two sons, and four-year-old Cocker Spaniel Crumble.
He said: “Another big part of my mental health recovery was my dog Crumble, so I knew I wanted to do something to raise funds for pets in some way.
“After spending some time researching animal charities, I came across PDSA and knew it was the right choice.
"My family wanted a dog for years until I finally gave in and got Crumble. I never thought I’d say it, but Crumble has changed my life for the better – we love spending time together and she's my best friend.”
Rob quickly realised how important pets are.
He said: “That companionship, the need to get out and walk them, socialising with other pet owners, it’s all so important for your health and wellbeing - whether that’s physical or mental.
“The thought of someone having to give up their pet because they couldn’t afford them is heartbreaking which is why I wanted to raise money for PDSA.”
The Royal Parks Half Marathon took Rob past many of the famous London landmarks including Buckingham Palace and Houses of Parliament.
“It was a brilliant day and I’m so proud of myself for completing it. But the best part - through generous donations from friends and family, I raised £490 for PDSA. Then the company I work for matched the amount, meaning we donated almost £1,000 to PDSA!”
