Star teenage apprentice Katelyn Mallyon is set to complete her comeback from serious injuries with a return to racing next month.

Mallyon has graduated from riding trackwork to competing in a barrier trial last week and said she was confident her return was on target.

Last season's champion apprentice, the 18-year-old was sidelined when she suffered spinal injuries in a race fall at Flemington in May.

Mallyon says she will be back competing before the end of the year if her rehabilitation continues to go well.

"I'm just taking it slowly but everything so far is going well," Mallyon told racingvictoria.net.au.

"My specialist is really happy with my progress and I'm back riding full trackwork.

"Everything that (Racing Victoria Doctor) Gary Zimmerman has wanted me to do I've passed with no trouble."

Mallyon missed more than two months of the 2011-12 season but still rode 58 winners - nine more than her nearest rival in the apprentices' title.

She is the the grand-daughter of triple Caulfield Cup-winning jockey Mick Mallyon.

Mallyon has had to overcome a fractured cheekbone and lacerated spleen and was in an induced coma for a week following the fall.
