After sharing a chuckle about Kate planting some Sweet William seeds, the Prince and Princess of Wales went head-to-head as they joined a lunchtime spin class during their visit to south Wales on Tuesday.
Despite wearing a midi skirt and heels, Kate was crowned the winner and handed a gold cup as she beat her husband William in the 45-second race. Take a look at their challenge in the clip below...

It's no secret that Wales holds a special place in Prince William and Princess Kate's heart.
The couple spent the early years of their marriage in Anglesey with the Prince later stating: "This island has been our first home together, and it will always be an immensely special place for us both."
And in June 2022, they shared their love of the country with their eldest children, Prince George and Princess Charlotte, when they visited Cardiff Castle during the Platinum Jubilee celebrations.
So, there's was no doubt the royals were excited to travel to south Wales on Tuesday morning.
William and Kate made the trip to help champion mental health initiatives and meet with local communities.
Their first visit was to the Brynawel Rehabilitation Centre to hear first-hand about the work they do to support those struggling with the effects of drug and alcohol addiction. They also saw new plans for a new 'therapy allotment' being built with the help of their Royal Foundation.

Kate looked beautiful for the engagement, dressed in a long cream camel coat, black boots and gloves, a white roll-neck and monochrome patterned skirt. She also carried a small black clutch and wore a daffodil on her lapel - as did her husband.

During the visit, The Prince and Princess met clients at the Centre and their families and learnt about how the current garden facilities and the outdoors are used as part of their therapy.

Among those the couple spoke to were recovery manager Claire Holloway, and trustees Marc Penny and Dai McBride. They were also greeted by a therapy dog, seven-year-old Great Dane, Ragnar. Stroking Ragnar, William commented on the dog's "big ears", while Kate said: "He must be very popular."
Kate was then invited to plant some 'Sweet William' seeds - and seeing the name of the flowers, William couldn't help but laugh. Volunteer gardener Vanessa Townsend helped Kate and told her: "They will flower in two years. I'll make sure you get some."
As the royals prepared to leave, two-year-old Cora Phillips presented Kate a bunch of daffodils. Cora's mother Michelle Phillips, from Llanharan, said: “Oh my goodness, I did not expect that in a million years.”
Turning to her daughter, she said: "We just met a Princess. We're never going to forget that."
Over time, Life at No.27 intend to create six therapy allotments and gardens across South Wales that will deliver mental health support to local communities.
The Prince and Princess's next stop was Aberavon Leisure and Fitness Centre to hear how sport and exercise can support mental health and wellbeing.
At the centre, the couple toured the facilities including a large indoor sports hall where young people and Welsh professional athletes including Harrison Walsh and Hannah Brier took part in an athletics and gymnastics session. Other facilities include a spin studio and an eight lane 25m swimming pool with a moveable floor.
Entering the cycling room, William apologised to the cyclists and said: "Sorry for ruining your spin class."
Before climbing on to his bike, the Prince joked to his wife: "You have got high heels on."
The Princess, who was wearing a cream top, checked skirt and black boots, said: "Not sure I am dressed for this."
During the race, Kate adjusted the gears and laughed: "Can I make it harder?"
After finishing, William, who was breathing deeply, joked: "Talk to you in a minute."
The Prince of Wales has become royal patron of the Wales Air Ambulance charity, Kensington Palace said.
The patronage was revealed ahead of William and Kate's visit to the charity's headquarters in Llanelli, on their final stop of the day.
It is the first Welsh patronage to be announced for William since he was given the title the Prince of Wales by the King.
The Wales Air Ambulance charity, which was founded in 2001, has completed almost 45,000 missions and is on stand-by 24 hours a day, 365 days a year.
William was an air ambulance pilot for the East Anglian Air Ambulance and a helicopter pilot with the RAF Search and Rescue Force based at RAF Valley on Anglesey.
