Both disabled and able-bodied athletes put their skills to the test at the iconic Dorney Lake on Saturday as they competed in the summer tri and para-tri festival. 

The festival is the second of the year organised by Chesham-based charity, Arctic One, which helps both able-bodied and disabled people to get involved in sport as well as helping to fight cancer through sport.

The summer festival, on July 28, saw athletes of all abilities taking part in different sporting events including a "super duper sprint" including a 200m open-water swim, a 5km bike ride and a 1.5km run. 

The super sprint saw athletes push themselves through a 400m swim, a 10km bike ride and a 2.5km run. 

Others took on the sprint - a 750m swim, a 20km bike ride and then a 5km run. 

Those really looking to push themselves even took on all three of the sprints. 

The event also hosted the British Paratriathlon Championships. 

Even novice athletes were encouraged to take part, with many taking on the challenge in a bid to raise funds for Arctic One. 

Karin Robinson got involved with Arctic One after meeting the inspiring athlete Andy Lewis, who scooped Olympic gold at the first ever triathlon in Rio 2016, through her rotary club, the Misbourne Matins. 

The 68-year-old, who often volunteers at Arctic One events with her husband Andy, was inspired this year to take on her first ever triathlon as part of the festival. 

So far, she has mananged to raise a staggering £2,411 for the charity. 

On her fundraising page, she said: "The courage, determination and perseverance of the para athletes, some as young as three years of age, has to be seen to be believed. 

"Watching them confront the challenges they have not only in sport but also in everyday life, I felt moved to try to match their courage and enthusiam by undertaking a triathlon myself- albeit it very mini.

"This has proved really, really tough - being 68 and my last sporting triumph being the mums' race at my children's school over 30 years ago. But whenever I feel like giving up, I simply think of our little Paralympians of the future."
