Amanda Holden led the masses as she posed for a snap ahead of the London Landmarks half marathon on Saturday.
The star, 48, was geared up for the big race as she excitedly warmed up by the start line.
The Britain's Got Talent judge was suitably dressed for the sporting occasion, dressed in a black and white zip up top and black sports leggings, as she joined fellow celebs and keen runners for the charity event.
She also rocked a black cap and pink trainers, while her running number and name was clearly displayed on her torso.
Amanda also came prepared for the race as she clutched a pair of sunglasses and had a pair of rose gold Beats headphones around her neck.
The star, whose blonde tresses were tied into cute plaited pigtails, looked happy and relaxed ahead of the event as she posed with a vest displaying her chosen charity - Tommys.org, which funds research into stillbirth, premature birth and miscarriage.
She is hoping to raise money to fund a full-time counsellor at Tommy’s Stillbirth Research Centre in Manchester.
