Kerrin McEvoy will return to the small South Australian town he put on the map with his Melbourne Cup win aboard Brew to help launch a charity bike ride in aid of the National Jockeys Trust.

Few people had heard of Streaky Bay until the first Tuesday in November, 2000, when McEvoy rode Brew to victory.

The township was also home to jockey Simone Montgomerie who was killed in a race fall on Darwin Cup day almost three years ago.

Her father Peter, the trainer of On A Jeune who ran second to Makybe Diva in the third of her three Melbourne Cups, is the driving force behind Cycling For Simone, a 3000km-ride which will take participants from Streaky Bay to Darwin over 26 days.

Montgomerie said he wanted to organise the ride in aid of the National Jockeys Trust which had been a source of support to him and his family including Simone's daughter Kodah after her death.

"The National Jockeys Trust and the industry as a whole came together to provide Kodah and our family with amazing support following Simone's death," Montgomerie said.

"We wanted to be able to give something back to the Trust and for the families and loved ones of other riders who are seriously injured or killed.

"A bike ride from Simone's home town of Streaky Bay to Darwin seems a fitting way we can do this - a big job - but something we can do to help celebrate Simone's life and make a difference at the same time."

The start of the ride on Sunday coincides with the official launch of this year's Melbourne Cup tour at Streaky Bay.
