City officials want to make it another seven in a row.

The national Commuter Challenge is set to happen between May 30 and June 5.

The city is hoping residents will once again help it take top spot in its category of municipalities with a population of 10,000 to 49,999 in the challenge by logging the number of kilometres residents walk, bike, bus or carpool to work through the week.

"Commuter Challenge is a national program that increases the awareness of the benefits of sustainable commuting and encourages Canadians to take action by walking, cycling, taking transit, carpooling or teleworking instead of driving alone to work,” notes a statement on the city's website.

"Communities and workplaces across Canada compete for the highest percentage of participation during this one-week national competition.”

Participants can register on-line at www.commuterchallenge.ca

There, they will log their trips by non-motorized or shared transportation and kilometres getting to and from work over the course of the week.

Along with competing as a municipality overall, individual workplaces have logged on to track their own individual progress and, in the case of the city and Northwestel Inc., once again compete against each other.

"After a really successful challenge in 2009, the city is ready to defend its title against Northwestel for another year,” Mayor Bev Buckway said in a statement Tuesday.

Last year's challenge saw the city defeat Northwestel with 389.22 kilograms of greenhouse gases saved, a fuel savings of $136.36, 36,994 calories burned, 1,812.8 kilometres saved, 42 participants of 300 employees or a 14-per-cent participation rate.

Meanwhile, Northwestel ended up saving 373.91 kg of greenhouse gases saved, $130.13 in fuel savings, 32,063 calories burned, 2,041.5 kilometres saved and 36 or 303 employees participating or 11.9 per cent.

The city held a news conference this morning at the Canada Games Centre to issue the challenge, with Northwestel more than ready to accept.

"We whole-heartedly accept the mayor's challenge and we plan to win,” said Paul Flaherty, Northwestel's president and chief executive officer.

"The Commuter Challenge is a great event, and we'll be rallying all our employees to get involved.”
