The forecast calls for sunshine on Sunday. Lots of it.

And that's very good for Cyclovia Tucson, the free event that closes city streets to encourage people to get out and exercise, whether it's on foot, bike or skates, and explore their community.

"We'd love to see Cyclovia become a tradition in Tucson where people embrace the idea of making it a car-free day," said said Kylie Walzak, the Cyclovia Tucson coordinator.

The event got its start in 2010 with a route that wound near the University of Arizona. It drew more than 10,000 people the next year when it moved downtown and into South Tucson.

Last year, turnout plummeted to 400 to 500 hardy souls who braved a wet, wintry storm.

"At one point it was raining ice," Walzak said.

Organizers wanted two events this year, in part to give a do-over to the sponsors and other groups that had signed on last year.

The first will be held on Sunday, connecting downtown to South Tucson.

The second will take place April 28, debuting a new route that connects midtown neighborhoods to the Pima County Loop multiuse path.

A series of five block parties are planned for both of the routes, with dozens of activities, entertainers, sculptures and soundscapes connected with a rubber-stamp treasure hunt, she said.

"Passports" will be provided with route maps at any of the Cyclovia Tucson information booths along the route. There are as many as 12 hidden places - hosted by musicians, dancers, DJs, artists and activity booths - to get your passport stamped.

"Part of our goal is for Cyclovia to happen four or five times a year, at the minimum, along different routes that rotate throughout the city of Tucson," Walzak said.

The idea is to to give as many parts of town the chance to experience Cyclovia as possible. "We'd love this to be once a month or twice a month."

Cyclovia Tucson is a project of Living Streets Alliance. Its supporting partners include Tucson, South Tucson, Pima Association of Governments, Pima County and more than 50 community groups, businesses and health-care providers.

It costs about $65,000 to put on one Cyclovia, which is financed mostly through in-kind and community donations.

This year organizers turned to Kickstarter and raised more than $8,500 thanks to 178 backers. The average pledge was around $50, which was the level at which people received a T-shirt.

Walzak said the total - about $7,700 after fees - will help pay for some of the fun activities at both events, including art activities, the rubber-stamp scavenger hunt and music.

The Kickstarter campaign also showed that Cyclovia has buy-in from the community.

People can still donate at the event, either directly or by buying Cyclovia items such as tote bags and T-shirts.

Traffic engineers estimate that 40 percent of all trips American make every day are 2 miles or less, and that we make 85 percent of those trips in our cars, Walzak said.

"We want to give people a chance to try out making those trips on foot or by bike in a fun, safe, carefree environment," she said.
