Team GB's dominance in the Olympic Velodrome continued on Day 9 at Rio 2016, as Jason Kenny beat teammate Callum Skinner in the gold-medal race to retain his Olympic Men's Sprint title.
It is the 28-year-old's fifth Olympic Gold, who could equal Sir Chris Hoy's tally of six in the Keirin on Tuesday.
With a guaranteed gold and silver for GB from Saturday's qualification races, all that was left to decide was who would take the Rio crown. Kenny was defending champion from London four years ago, while Skinner was the pretender to the throne.
As participants in the gold-medal winning Team Pursuit quartet, both men had been the best in the field in during progression and it was now a race to determine who would take two Olympic titles away from Brazil, as the fastest man on two wheels.
Both came through the qualifying rounds without losing a race into the semi-finals, intriguingly it was Skinner who remained unbeaten in his semi-final versus Australia's Matt Glaetzer, whilst Kenny had to come from behind in his race versus Denis Dmitriev of Russia.
Kenny asserts dominance over pretender
Ironically it was 8 years ago back in Beijing 2008, when another all-GB gold race, saw Kenny edged out for the top of the podium by six-time Olympic gold medalist Sir Chris Hoy. This time around, it was the Bolton rider with the bullseye on his chest, as 23 year-old Skinner challenged for his title. As World Champion from March in the Lee Valley VeloPark, Kenny was still the man to beat.
In the first of a three-race final, the Scot opened up an early lead with a lap to go. Kenny surged on back straight however and rounded the final bend, slipstreaming past his fellow Brit and powering ahead to cross the line first, as Skinner lost his first race of the sprint event.
Skinner looked to take it to a decider, but after Kenny took the to front this time, the defending champion's strength and experience told as Kenny won his fifth Olympic gold.
In the bronze-medal race it was Dmitriev who claimed the third place, outclassing the Australian in winning his best of three contest, two nil.
