The three generations crossed the finish line together yesterday with a time of about 50 minutes in the Tour de Femme, a 20km women's-only cycling event in Canberra.

The three are part of Team Pill, a group of social riders.

They know each other socially as their children attended the same school.

For them, cycling was ''the pill that keeps us going, keeps us in touch and keeps us fit'', Mrs Davies said.

Members of Team Pill like to take along their daughters when it's time to contest the Tour de Femme. Mrs Davies calls herself ''the only matriarch''.

An avid rider since her school days, she had to put the brakes on when raising her seven children left little time for cycling.

On her 50th birthday, her children gave her a ''super bike''.

''I thought it was such a compliment, [for them] to think that I would use it.

''It transpires that they were absolutely right.

''I've had a couple of bikes since then, I'm lusting after another one.''

While the family crossed the line together, Mrs Davies was out in front for most of the ride.

Her family agrees she's the most competitive.

Upon finishing the Tour de Femme, she cycled home.

Each loves something in particular about cycling.

For Ms Montgomery, it's the camaraderie; for Siena, it's ''the rush of wind on your face''.

For Mrs Davies, ''it's the total freedom''.

''You're out there in this beautiful world, it's whizzing past and you can see it all,'' she said.

''You are not dependant on anyone but yourself. There is no noise from motors. It's just you and the elements. It's beautiful.''
