She got in some last minute training under the watchful eye of Good Morning Britain co-host Piers Morgan earlier in the day.

But Susanna Reid looked like a woman who was more than up for the challenge when she took part in the Tough Mums event alongside a host of hardcore mothers at Belvoir Castle in Grantham, Leicestershire, on Wednesday afternoon.

The 45-year-old broadcaster proved she was indeed a tough mother as she braved a five kilometre obstacle course alongside 100 other mothers.

Lets do this! Susanna Reid looked like a woman who was more than up for the challenge when she took part in the Tough Mums event alongside a host of hardcore mothers at Belvoir Castle in Grantham, Leicestershire, on Wednesday afternoon

The TV presenter looked the epitome of a warrior as she and co-host Kate Garraway dashed to the start of the course with strips of black paint brandished across their cheeks.

Despite the strenuous nature of the challenge that lie ahead, the sprightly stars seemed in the highest of spirits with their beaming smiles and vivacious can-do attitude.

Leading the way, Susanna took on the course in black leggings and body amour, though concealed the fitted nature of the look beneath an baggy red T-shirt.

Harder than ever: The course featured some of Tough Mudder's most exciting signature obstacles including King of the Swingers, Pyramid Scheme, Mud Mile and the all-new Frequent Flyers Club

Not afraid to get her hands - or indeed her entire body - dirty, the journalist's pristine fitness garments didn't stay that way for long and were plastered with mud by the time she crossed the finish line alongside her teammates.

The same could be said for Kate, whose once yellow T-shirt was ridden with grime once she re-joined Susanna at the end of the course.

The girls were just two of a host of Good Morning Britain stars who took part in the physical challenge as Richard Arnold, Ben Shephard, Ranvir Singh, Sean Fletcher, Alex Beresford and Dr Hilary Jones also worked up a sweat.

Giggles: Susanna also maintained her smile and even found the energy to laugh during the event

It's over! Unsurprisingly, laughter wasn't in short supply when Susanna's team finally completed the strenuous obstacle course

Celebrity mums Sinitta, Julia Bradbury and a group of other inspirational mothers were also chosen by the programme to take part.

Before taking part in the assault course, Susanna prepared for the gruelling challenge under the watchful eye of Piers Morgan as she performed push-ups in a floral dress and heels in the Good Morning Britain studio.

The brunette beauty was clearly keen to cram in some last-minute exercise ahead of the 2016 Tough Mums event.

Susanna dropped to the GMB studio floor in her form-fitting frock and as the camera returned from the ad-break she comically counted past the 100 mark as Piers pretended to whip her into shape.

Her suited and booted co-host was in personal trainer mode as he growled: 'Come on! Harder!' as Susanna worked up a sweat.

The ever-enthusiastic Kate Garraway, 49, was already at the course base camp in Grantham, and along with other willing participants demonstrated one of the obstacles.

Whoops! Richard found himself in some rather compromising positions during the challenge

Still owning it! Even when forced to swim through murky waters, Susanna still manged to maintain her poise

Working as a team, the mums formed a human pyramid against a slippery 10 ft sloped wall in order to help Kate scramble to the top.

Clad in colourful funky leggings and a shocking pink vest top, Kate tentatively climbed the slippery wall and was eventually pulled to the summit after slipping near the top.

Sinitta and presenter Julia Bradbury will be among the brave mums tackling the challenge, while Liberty X's Jessica Taylor had originally meant to take part but had to withdraw on doctor's orders following a hoverboard incident.

Clubbing together: Comradery certainly wasn't in short supply during the challenge

Ben Shepherd attended the last challenge and wasn't going to pass up the opportunity to be involved again, tweeting: 'Charging south from Newcastle for our #TOUGHMUMS challenge. It's wet it's cold and it's gonna be bloomin muddy!! Can't wait @GMB'

The 100 participants each had to apply to take part and were required to be either a mother or mother figure who could give an example of what made them tough.

Speaking after the challenge, Susanna Reid said: 'Tough Mums 2016 was even harder than last year, there were new obstacles and there were new fears in facing them! It was incredibly hard but we all encouraged each over, worked as a team and got round the course.

'Some of the women taking part today have overcome, or are still trying to overcome huge personal obstacles- they're such an inspiration and thinking about that really helped when I was faced with dark muddy tunnels or deep icy water!'

Working up a sweat: Susanna prepared for another gruelling Tough Mums challenge under the watchful eye of Piers Morgan as she performed push-ups in a dress and heels earlier in the day

While Sinitta said: 'It was one of the toughest and most rewarding things I have ever done, surrounded by incredible tough woman.'

The course featured some of Tough Mudder's most exciting signature obstacles including King of the Swingers, Pyramid Scheme, Mud Mile and the all-new Frequent Flyers Club.

And Kate Garraway added: 'This year I think was even better than last year, it's just so much fun hanging out with brilliant women all day. Everyone helps you through the obstacles and you end up laughing through your fears.'
