This time last year John Sadler at 60 was embarking on yet another sea change in his already colourful yet successful training career.

Sadler had just split with former partner Troy Corstens and was returning to Aquanita Racing, a business operation that he had formed many years ago.

But the former Colac horseman has managed in the last 12 months to shrug off the last stages of depression.

Before joining Aquanita, Sadler had been struck down by depression that saw him leave racing for a number of months.
