Already familiar with the grounds, it's not the first time that Mark and Florence have attended the horse trials, as they stepped out to support Zara at both Thursday's and Friday's events.
It's hardly surprising that Mark has been in attendance all week, given his close relationship with his daughter, not to mention his shared love of the sport.

A former member of the British equestrian team, back in 1972, Mark and his fellow teammates won the gold medal at the Munich Olympic Games.
His reported girlfriend, Florence, is also an experienced equestrian and was previously in a relationship with Thomas Ryckewaert, who ran the Waregem horse trials in Belgium until his passing in 2019.

While their reported relationship has not yet been confirmed, the pair may possibly have met in 2020, when Mark, the ex-husband of Princess Anne, was tasked with designing a cross country course at Waregem, which was being run by Florence.
Prior to his reported romance with Florence Standaert, Mark Phillips was previously married to Princess Anne from 1973, with the couple later divorcing in 1992.
