William and Kate, both 35, kicked off the day’s events with a visit to the Jaguar Land Rover's Solihull Manufacturing Plant, where they tried their hand -- rather successfully, we might add -- at off-road driving.
The royal duo were also given an overview of the site before viewing the assembly line, hearing about the manufacturing process and meeting staff and apprentices at the location.
Kate -- who is pregnant with her third child, due in April -- opted for black coat with military-inspired accents by Goat and a pair of knee-high Russell & Bromley boots for the occasion.
The couple next made their way to Aston Villa Football Club where a quick change of clothes readied them for a more hands-on engagement.
The Duchess swapped her designer coat for a black turtleneck jumper, bright-red puffer jacket, skinny jeans and trainers. Of course, all eyes were on the royal’s growing baby bump which was clearly visible beneath the form-fitting look.
Meanwhile, the Duke changed out of suede boots and into a pair of brightly-coloured sneakers. He also added a navy puffer jacket, which would have provided a touch more flexibility than the blazer he had worn earlier in the day.
The expectant parents met with employers and sporting groups before taking part in on-pitch training session with local children.
Sidrah Batul, a pupil present at the event, later spoke about her interaction with Kate.
“She was asking me if I enjoyed it and I said I was having a lot of fun,” the 10-year-old said, according to The Daily Mail.
She added: “She's so kind and pretty.”
Later in the day, William and Kate stopped by Acme Whistles -- the creator of the first police whistle.
The mum to Prince George, four, and Princess Charlotte, two, has been forced to miss a number of important events in recent weeks -- including her son’s first day at school -- owing to extreme morning sickness or ‘hyperemesis gravidarum,’ the same nasty condition she battled while pregnant with four-year-old son, George and two-year-old daughter, Charlotte.
But it looks as if she’s on the mend!
Kensington Palace have begun to once again announce the royal’s appearances ahead of time, suggesting that she’s feeling well enough to schedule and keep forthcoming engagements.

Kate and Wills third little prince or princess is due to arrive in April 2018.
And while they haven’t yet confirmed the exact due date, there’s a chance the newest royal addition could share their birthday with their great-granny the Queen, who will celebrate her 92nd on 21 April.
Or, if the royal bub were to arrive later in the month, their grand entrance could coincide with the duo’s seventh wedding anniversary on 29 April.
We can barely wait!
