At just 23 years old, Angus Leckonby has already made history — and he’s not finished yet.

A proud Special Olympics Great Britain athlete from Octon, East Yorkshire, Angus captured global attention in 2025 by setting three Guinness World Records, redefining what is possible for athletes with intellectual disabilities:

Fastest Marathon completed by a Person with an Intellectual Impairment (Male)

Youngest Person with an Intellectual Impairment (Male) to complete a Marathon

Youngest Person with an Intellectual Impairment (Male) to complete a two-mile Open Water Swim

Living with autism, verbal dyspraxia and an intellectual disability, Angus has never let labels define his limits. Instead, he has built his journey on discipline, resilience and an unwavering belief in his own potential.

Having broken records on the world stage in 2025, Angus is now setting his sights even higher. In 2026, he aims to break his own Guinness World Record for the fastest marathon by a person with an intellectual impairment, starting with the TCS London Marathon on Sunday 26 April, where he hopes to beat his previous time of 3:36:38.

But for Angus, these record attempts are about more than numbers on a clock. They are about representation, inclusion and inspiration. By taking on some of the toughest endurance challenges in sport, Angus is showing that athletes with intellectual disabilities belong on the biggest stages — and can deliver extraordinary performances when given the opportunity.

Angus trains year-round with Yorkshire Wolds Runners alongside his local Special Olympics GB club, following a demanding programme that combines endurance running and open-water swimming. His weekly schedule includes multiple training sessions across both disciplines, continually building strength, race awareness and confidence.

With the experience of three Guinness World Records behind him and a relentless commitment to improvement, Angus enters 2026 stronger, more focused and more determined than ever to push his boundaries once again.

Additional Guinness World Record attempts will be identified and applied for later in the year, as Angus continues his journey of challenging perceptions and rewriting expectations.
