Champion reinsman Chris Alford has produced the greatest season by an Australian driver, officially breaking new ground with win number 389 at Geelong tonight.

With a victory on $13-shot Dependlebury in the Flying Brick Original Cider Pace, Alford moved past Daryl Douglas' season record of 388 wins that had stood since the 2007-08 season.

“It’s a mark that may never be beaten," caller Dan Mielicki told Trots Vision in the wake of Alford's win. "400 is in danger, and that’s a record that will stand for a very, very long time.”

Alford entered today one shy of Douglas' record but won with his family's two-year-old trotting filly Sleepee at Stawell today and then made the 210km trek to Geelong to steer Dependlebury to an against-the-odds win.

The achievement attracted much praise from his peers and trots fans.
