The royal announced last week that she and rugby player husband Mike Tindall are expecting their first child together later this year, but that hasn't slowed her down when it comes to her equestrian career.
On Saturday, (13 July), the mum-to-be looked in good spirits as she took part in a match at the Army v Navy Rundle Cup Polo in Tidworth, Wiltshire.
Dressed in a pale blue polo shirt on the hottest day of the year so far, the royal was cheered on by her proud husband, who watched from the sidelines.
She later changed out of her blue polo shirt into a loose fitting gold T-shirt and navy shorts.
There was no rest for Zara as the next day she was back in the saddle again, this time competing at the Brightling International Horse Trials in East Sussex.
Zara's decision to continue riding while pregnant has sparked plenty of debate among the public, after she fell from her horse last week.
A spokesperson, however, said Zara was "fine" and insisted that although she will continue riding, she "would never put her pregnancy in jeopardy".
The representative said: "She is following all medical advice from her doctors and is listening to what the doctors are telling her."
