The competition was held over two days and featured many big name athletes, including 2016 women’s world champion Sarolta Kovacs.
The event started with the riding discipline and 18-year-old Bryson made a solid start with 264 points.
She then came into her own in the fencing, recording 25 victories – two more than anyone else – and suffering just seven defeats.
On the second day of the competition, Bryson recorded a time of 2:20.63 for the 200m swim, which meant she headed into the final combined laser-run discipline in sixth place.
Despite some strong shooter, Bryson did drop down to eighth, but it was still an impressive finish at a top senior international event.
Her GB team-mates Charlie Follett, Georgia Hannam and Georgia Pipes finished 11th, 21st and 31st respectively.
