Moffat Academy pupil Shelby Watson, 17, won her mini marathon category in London on Sunday, even beating her own personal best.
The T33 wheelchair racer shot to victory while raising funds for the Dumfries branch of the Multiple Sclerosis Society, who she has so far raised over £500 and counting for.
Her dad, Ross, said: “Shelby was over the moon. When she crossed the finish line she had no idea she had won.
“She told us that at one point she realised no one was in front of her and no was behind her but she had no idea what this meant.”
On Monday the teen gave away her medal to a primary aged supporter who gifted the athlete with a good luck charm before her race.
Explaining the reasons behind her actions, Ross said: “A young girl from Dalbeattie, called Lucy, approached Shelby recently when she was profiling at Tesco in Dumfries and gave her a necklace. She said it would give Shelby good luck.
“Shelby promised the girl if she placed in the race she could have her medal.
“Sure enough Shelby wore the necklace on Sunday and she won her race, Lucy was right about the necklace.”
Shelby decided to pay Lucy surprise a visit at Dalbeattie Primary School on Monday to present her with her London Mini Marathon medal in front of class mates.
She said: “I promised Lucy if I was placed in the Mini Marathon I would give her my medal and I was so pleased to be able to keep that promise.”
Ross said: “Lucy was so happy to see Shelby. Being able to give her the medal made winning the race all the more sweeter for Shelby.”
