A dad of newborn twins, and business owner from Yate, is taking on the London Marathon for charity and attempting to break a Guinness World Record in the process.

Andy Taylor, owner of Blast Fitness in Yate, is taking on the 26 mile run around the capital this Sunday but there is a twist.

He will be taking part dressed in a unicorn onesie.

"I've always loved the London Marathon, the atmosphere there is unlike anywhere else and I was one of the lucky few to get in on a ballot place this year," Andy said when speaking about why he decided to take on the run.

Not only will he be attempting a world record but Andy is also fundraising for local charity Jessie May, an organisation that helps provide care at home for terminally ill children.

Andy and his wife Charlotte welcomed twins, Evelyn and Jackson earlier this year, but Andy revealed that were some issues with the pregnancy.

"I wanted to help a small local charity," Andy explained.

"Throughout Charlotte's pregnancy, we had a few little scares and were in hospital for scans most weeks, then when the twins were born Evelyn had to spend a few days in intensive care.

"We were lucky enough to be the ones who came home with two healthy babies, but I can't help but think about other people. Jessie May do amazing work for those families."

Andy will be looking to break the Guinness World Record for fastest man as a mythical creature category, to do this he will need to finish in a time under 4 hours.

"The main question I get asked is why a unicorn, and I don't have a good answer," Andy revealed.

"I really don't take myself too seriously and so I'm happy to do anything to make myself look a bit silly.

"Also my kids still look at me like I'm their world right now, but give it a few years this will be so embarrassing for them.

"I've been doing plenty of runs in thermals to get used to the heat, the runs in the outfit were so much fun, the people of Yate are amazing and really spurred me on."

This will be the third time that Andy has taken on the London Marathon, with his last effort coming five years ago.

On that occasion Andy took part with Charlotte, actually proposing at the finish line.

"The last time I ran the marathon was when our engagement was caught on camera so it makes it such a special event for us," Andy said.

"To be going back again 5 years later, married with twins, feels amazing."

Andy has set himself the fundraising target of £1000 for the run this weekend, and has already raised over half that amount.

"I'm hoping to raise £1000 for Jessie May," he said.

"Everyone at Jessie May is brilliant, they have been so supportive to me on my fundraising.

"We are already half way there, I can't tell you how grateful I am to every who has sponsored me so far, it's genuinely such an amazing feeling to know how many generous people we have in our area."
