About 30 well-bundled cyclists and a handful of police joined Councillor Adrian Heaps, chairman of city council's cycling committee, yesterday to brave frigid air and warnings of heavy wind gusts as part of a campaign to promote winter cycling. The ride from City Hall to Metro Hall - billed the 'Coldest Day of the Year Ride' - attracted hardy souls such as Smokey Dymny and his Dutch-designed 'long john' cargo bike. While Mr. Heaps has spearheaded plans to speed up the painting of bike lanes, Toronto has lower rates of year-round cycling than some other cities with similar or worse climates.
