TV personality Jess Impiazzi led a host of celebs as they competed in the London Landmarks Half Marathon on Sunday.

The Ex On The Beach star, 32, beamed as she posed for pictures with other famous faces including Abbie Quinnen, 24, and boyfriend AJ Pritchard, 27.

Hoping to raise funds for the Guide Dogs charity, reality star Jess rocked up in a branded t-shirt – a cause she held dear when her mother lost her sight as a teenager.

Also captured ahead of the 13.1 mile run was Abbie and AJ looking in good spirits and even sharing a sweet kiss for cameras.

The couple ran for charity CW+ to raise money for Chelsea and Westminster Hospital.

They chose to support the incredible work of NHS hospital medics, who saw Abbie with her own eyes in a horrific accident last year for second and third degree burns.

Meanwhile, AJ’s dancer brother Curtis, possibly adding a touch of sibling rivalry to the event, was also on the starting lineup.

Elsewhere at the circuit, McFly’s Harry Judd was hard to miss in striking orange trainers and a turquoise Nike vest, and just as bright was ex-Towie star Charlie King in a bright yellow windbreaker.
