Indoor British Championships: Toby Harries and Adelle Tracey win
Teenager Toby Harries won the men's 200m title at the Indoor British Championships in Sheffield.
The 17-year-old finished strongly to win in 21.33 seconds from Ben Snaith, in second, and third-placed David Lima.
"I didn't even think I would make the final so to get the gold medal is literally breathtaking," said Harries.
Adelle Tracey, 22, caused an upset by winning the women's 800m, as Leah Barrow was second ahead of Lynsey Sharp and Jenny Meadows.
Tracey, one of six teenagers to light the Olympic flame at the London 2012 opening ceremony, said: "I'll be so happy to wear my first senior vest and to do it so early in the season is amazing.
"I'm working part time as a freelance hair and make-up artist and it's good because it fits around my training. I do prosthetics and model making as well, so it's very diverse.
"I did Lenny Waite's wedding this summer and Andy Vernon's wife and Gemma Hillier-Moses (all fellow athletes), because it works very well with training, it's just one morning. But I've done stuff for Dr Who and Top Gear."
The event is being used to select the Great Britain team for the World Indoors in Portland from 17-20 March.
Following the first day of the trials on Saturday, there were 17 finals on Sunday and selectors will meet on Monday before naming the team on Tuesday.
In the women's events, European champion Tiffany Porter triumphed in the 60m hurdles with a time of 7.98 seconds as Serita Solomon came in second and Lucy Hatton in third.
Hannah England eased to 1500m victory, while Louise Bloor claimed the 200m crown and Meghan Beesley won the 400m final.
Sinead Gutzmore was already in first place in the triple jump and reached a 13.35m personal best with her last effort to round off her win.
