Well she is a mum now so her role has changed, but she was working out of Cheltenham racecourse for a while around her training for the equestrian comps she took part in....she was world champion a few years ago. as already said, that must have taken a huge amount of work.
She missed the Jubillee celebrations the other year as she was in Eire doing a qualifier IIRC. That must have been tough from a family perspective irrespective of what anyone thinks of the royals..they are still people at the end of the day.
