Amanda Holden showed off her fabulous figure in a pair of skin tight leggings and matching sports top as she took part in this morning's London Landmark's Half Marathon.
Despite having just run 13 miles, the Britain's Got Talent judge crossed the finishing line with immaculate make-up and her cute plaits still in place.
Her vest displayed her chosen charity - Tommys.org, which funds research into stillbirth, premature birth and miscarriage.
Amanda, 48, is hoping to raise money to fund a full-time counsellor at Tommy’s Stillbirth Research Centre in Manchester.
The project, called Theo's Hope, is named in memory of her son Theo, who was tragically born stillborn in 2011.
Other celebrities who ran the half marathon include Liberty X's Michelle Heaton, singer Jake Quickenden, Love Island's Eyal Booker and Frankie Foster, and TOWIE's James Lock, who were running on behalf of Cancer Research UK's team Jog On To Cancer.
