In an unusually small field for the senior event, Vélo Sport rider Jardine soon broke clear and built up a lead of ten seconds after five laps.
He increased it to 18 seconds before being gradually reeled back in after 30 minutes of freedom.
However, after another three laps he broke clear again, this time with Caesareans’ Vince Peron.
With neither Ali Cann nor Jim Garrett willing to take up a tough pursuit, the breakaway pair soon built up a lead of one minute with five laps to go.
With the drizzle now falling Jardine and Peron pressed on, the gap widening each lap.
Into the finishing straight Peron was no match for Jardine who crossed the line several lengths clear.
Just under two minutes later Ali Cann outsprinted Garrett for third.
A much larger field contested the shorter race for veterans, ladies and juniors.
Caesareans’ Mike Harris was a clear veterans’ winner, constantly stretching out the bunch with his efforts at the front.
He led by 15 seconds with just three laps left and the main group of 12 riders were only contesting second place.
Harris won by over half-a-minute and was able to watch the hectic sprint for second place, with Vélo Sports’ Andy Munns just holding off Steve King and Mark Wunsch.
First junior home was Vélo Sports’ Peter Ilton, who led in a small chasing group a further minute down.
The group included Caesareans’ Sarah Smith, who took the ladies award, after having survived a front wheel puncture midway through the race.
