When the Women Riders World Relay motors into Tamworth this weekend, ready to pass the baton at the end of the day's ride, the Gunnedah woman wouldn't miss it for the world.

She will join - either in reality or in spirit - a reported 17,000-plus riders who have been taking part along a route that started in Scotland in February.

And it'll be a girls' weekend with a difference, as her Tamworth-resident mum Cheryl Carpenter will set off with her, too.

"The baton's gone all over the world, and it's a once-in-a-lifetime chance, something I can do with my mum," she said.

"And God bless my husband: he's staying home for two days with the kids so I can do it."

The relay has already gone through more than 50 countries in Europe and Asia.

The event was started to celebrate, encourage and raise awareness of female motorcyclists, whose numbers are rising.

"I would have loved to do [the world trip] if I had the money," Mrs Roberts said.

"I've been following it since the itinerary first came out and said, 'Mum, do you want to go?'...

"Mum's been riding for about 45 years but is only just recently getting back on the bike, and I've been riding for about 10 years."

Mrs Rodgers said she would encourage other women to give motorbike riding a go - "It's just freedom and break from the kids and break from the world, basically: you get on your bike and you just go."

But there needed to be more support, services and gear for women.

"You go into a motorbike store and it's mainly males, male merchandise; there's not much range to choose from ... we need clothes too and safety, too," she said.

The Australian section of the relay started in Burswood, WA, on Sunday, August 25 - day 180 of the global event.

Sunday's legs will go from Dubbo to Tamworth, then Tamworth to Glen Innes.

The final Australian destination will be Ramsgate Beach, NSW, on Friday, September 6.

This will be day 192 of the world event, which will conclude in the United Arab Emirates in January 2020.
