Last year Luke Traynor took sixth place in the 10K, but this year the 18-year-old took first place in 31 minutes 41 seconds.
The youngster of Giffnock North Amateur Athletics Club stormed through the finishing line despite the heat, while Michael Deason came second at 31.56 and Robert Gilroy came third at 32.02.
While the men's 10K winner is soon to start a degree in environmental management, the winner of the female 10K is already a student of dentistry.
Elspeth Curran, 22, came first in 35.09, Jennifer Emsley second in 36.58 and Kirsty Husband third in 37.03.
Luke Traynor said: "It is pretty incredible to have won because I just wasn't expecting it at all, although I have been a runner for three years now. After winning I'm now inspired to try and get into the Great Britain cross country team."
The music of the Kings of Leon and Katy Perry blasted out at the finishing line at Glasgow Green, and the crowds of spectators grew as the day unfolded.
Elspeth Curran said: "On the day of a race you never know who else is going to be there that you will have to compete against. But I got into the competitive spirit and it paid off. I want to be the best I can be."
As an estimated £1.5 million is expected to be raised for a variety of charities from the event, model Nell McAndrew was triumphant to have helped raise £4000 for Save the Children.
The 37-year-old said: "This is my first experience running around Glasgow and the people taking part along with the crowds were just doing an absolutely amazing job, especially when everyone has different levels of fitness.
"The personal challenge of finishing such a race is enormous and I'm so glad we got to raise money for such a good cause."
Entrants for this year's races have come from all across the world, including Australia, the Congo, Holland, Uruguay and the USA.
But it was Kenyans who hogged the limelight in the half marathon, with Joseph Birech's first ever run in Scotland resulting in first place in the time of 1.02.26.
Bernard Kipkemoi Rictich from Kenya came second in 1.02.28 and Rashed Essa Ismail from Qatar third with 1.02.10. Filomena Chepchirchir from Kenya was first among the women in the half marathon with a 1.09.26 finish, while Kenya's Hilda Jepchumba Kibet came second with 1.09.36 and Holland's Mayumi Fujita third in 1.11.51.
Many spectators were at the races to show support to their family and friends, and some travelled long distances.
Spectator David Shields-Lewis said: "My wife and I travelled from Dunoon to get here and got the ferry at 5am so we could see our daughter in the race."
Beating personal bests was also on the agenda for some.
Amanda Fryer, a half marathon participant, said: "Last year my finishing time was 2.05 and this year I was 1.55, so I'm elated and feel over the moon."
While a Shrek character, Batman and Superman graced the race, others preserved the memory of loved ones with poignant images on their T shirts.
With 15 other runners from Calton Athletic Recovery Group, Colin Martin ran the half marathon in memory of the group's founder, Davie Bryce.
He said: "It was nice to run in such a great person's memory and the atmosphere during the race was amazing and the cheers from the crowds really carried us through."
