Dressed in a cute cream coat, navy headband and matching purse, Mia was also seen reapplying her lip gloss before the big race began.
Mike, 44, who shares younger daughter Lena, 4, and son Lucas, 1, with Zara, 41, recently admitted Mia “goes absolutely mad” if she’s beaten in games and running races against her old man.
“I think it’s a balance and I’ll let Mia win occasionally,” Mike said on British show Loose Women.
“But I make sure to beat her as well because she has to be able to take losing.”
Mia cheered until she was hoarse.

"Then we figured out that we both quite like getting smashed. It was a good start."
