Silver Sammi is no more.

"Gosh, it'd be amazing to win a gold medal," she told the BBC on Tuesday, after coming second in the 1500m. She did not have to wait long to experience that feeling.

The gusto with which she rang the victory bell in the Stade de France was a clue to just how exciting and emotional it was to upgrade her medal collection.

"I sobbed the whole way round my victory lap, just sobbed the whole time," she said.

"Tokyo was my first Paralympic medals but with nobody in the stands and that for me was pretty heartbreaking. I've got 29 people out there with posters of my face. To do it in front of all them is so incredibly special because although it's an individual sport I have a huge team besides me."

Kinghorn was 14 when she broke her back in an accident on her family's farm in 2010, snow and ice falling from a roof and crushing her.

She spent six months at the Southern General Hospital in Glasgow before being told she would never walk again.

"When I had my accident, my body was torn down to nothing. I rebuilt it in training and that was something that helped me accept this new me," she said.

"My physio at the spinal unit in Glasgow, without her I would not be here now. She saw something in me. I always loved sport before my accident and she got me into trying lots of different sports.

"I went down to try wheelchair racing and Ian Thompson, Tanni-Grey Thompson's husband, said to me 'Oh, you could be good at this.' Straight away that was a switch. Something quite traumatic had just happened to me and I didn't know if I was ever going to be good at anything ever again. I remember thinking 'OK, great, that's what I'm going to do.'"

Kinghorn's first Paralympic gold follows three world titles, the most recent over 100m in Paris last year when she also got the better of Debrunner.

There could be more medals in Paris for both of them. After the 400m on Thursday, Kinghorn has the 4x100m universal relay on Friday while, incredibly, Debrunner will contest the marathon on Sunday.
