David Haze has faced down some challenges in recent years.

After all, you don’t get to achieve four world records without pushing yourself to the absolute limit.

But the Stand Up Paddleboard (SUP) adventurer has just completed his toughest challenge to date – and bagged his fifth world record in the process.

Tackling the non-tidal River Thames in one go.

That’s 208 km – or 129 miles – of continuous paddling from Lechlade to Teddington Lock.

The aim was to beat the previous record of two days, 14 hours and eight minutes.

And David achieved it – by ten hours.

But the 36-year-old, who lives in Branksome, Poole, said: “This was by far the toughest challenge that I have ever undertaken and one I am truly proud of.

“It was so nice to connect with the water and be at one with my surroundings.

“But after 40 hours of continuous paddling, I started to become very delirious and knew for my own safety that I had to pull over for a quick nap.

“There were two key moments where I was ready to throw the towel in.

“But this whole ‘adventure’ journey that I am on has taught me so much about myself.

“In those two moments I knew I was much more than a quitter.

“I knew I was stronger than what my mind was telling me.

“I fought through the suffering only to emerge a better version of myself with another world record added to my belt.”

David, who goes under the name Nomadic Paddler, was raising money for Alliance of Sport.

The charity uses the power of sport in the criminal justice system to help tackle reform and rehabilitation.

He is already nearly four fifths of the way to his £3,000 target.

David, a criminal justice consultant, said: “The power of adventure and sport has truly transformed my life for the better, giving me purpose, drive and an opportunity to understand myself once again to live a fuller life.

“We all need to come together to make a difference, bringing down the reoffending rate in this country, creating safer communities and harmonious environments for all of us to live in.

“As a society we need to support those that have fallen and not let them become lost in the system any longer.

“Old dogs can learn new tricks and I want show how we can all change and grow as individuals.”

David’s previous four world records were achieved after paddle boarding the length of the UK’s four longest lakes on four consecutive days and in a record time.

He started at Loch Awe in Scotland (25 miles), then Lake Windermere in England (12 miles), over to Lough Neagh in Northern Ireland (19 miles) and finishing with Llyn Tegid in Wales (4 miles).

Next for David is an attempt on the world record at Lough Corrib in Southern Ireland next month, followed by Iceland’s longest lake the following month.

And then, in May next year, the really big one dubbed ‘Untamed Beasts’.

He’ll attempt to set the world record for the fastest time paddled across 33 lakes, in 33 countries across Europe in 66 days.

David said: “This is something where I’ll need financial sponsorship and it would be great to work with local companies.”
