Since April, he's lost 10 kilos riding his bike between home in Turner and work in Woden.

"I feel much better for it," Mark, 50, said.

"I'm also saving a lot of money in parking and wear and tear on the car."

The Cycle Works program was Mark's initial inspiration. It is a month-long challenge to encourage people to ride their bike to work, the next one starting on Thursday, March 1.

Pedal Power CEO Ian Ross said autumn was a great time to cycle in Canberra.

"We know it takes time and persistence to form new habits, so we have developed a month-long challenge to help people work cycling into their daily lives," Mr Ross said.

"It's a free program - you can register online, set and track your goals on a leader board, sign up with friends and colleagues and encourage each other. And there's great prizes to be won including a Trek bike."

And Mark reckons it has been a joy to be back on the bike, with no major issues on the roads.

"I find that Canberra motorists get a bit of a bad rap," he said.

Other programs are being offered by Pedal Power include, for the absolute beginner, the Cycle Well program which teaches the very basics and New Horizons which is a longer course for riders who want to develop skills and confidence.

"I've loved listening to the stories of people who've been through these programs and hearing how their lives have been transformed through cycling," Mr Ross said.

" We've had people who've never been on a bike and are now enjoying the freedom of regular riding, and others who've talked about how much healthier they are and how much weight they've lost while riding to work."
