Brocklesby Hunt Pony Club rider Daisy Williams made the six-hour lorry journey to Kelso, in Scotland, to compete in the annual Northern Mini Regionals Tetrathlon.
The nine-year-old was there to represent the Eastern England team with her pony Smokey, and competed against 25 other children who had travelled from Wales, the Isle of Man and Northern England.
Daisy led at the end of Saturday following the pistol shooting, 1km run, and swimming disciplines.
She held her nerve going into Sunday’s cross country competition day, and was one of only six riders who went clear around a course set in the grounds of Pallinsburn House, in Ford, Northumberland.
Daisy said: “I am so proud of Smokey, I can’t thank him enough.
“To come here and compete is amazing, but to win is a dream come true!”
A delighted Daisy finished first overall and took the prizes of best shoot, best swim, and fourth place run. She was also placed into a mixed area team which finished third.
Daisy’s mum, and ‘travelling groom’, Jill said: “Daisy trains hard for these competitions, and I’m so pleased for her and the pony when it all comes together for them.
“She made lots of friends up in Scotland, but it’s back to reality today as she’s straight back to school.”
Daisy is taught competitive swimming at Cleethorpes and District Swimming Club under head coach and former international swimmer, Matthew Allison.
Her busy training schedule also includes regular target practice at North East Lincolnshire Target Club.
“With shooting, running, riding and swimming there are so many areas that the children need to be good in that finding time is the hardest thing,” Jill added.
