A few hundred Toronto cyclists took to the streets Monday, riding in to work as part of the city's 25th annual Bike To Work Day.

Under sunny skies, riders gathered at marshalling points around the city to form a rolling parade that moved into the downtown core for a free pancake breakfast at Nathan Phillips Square.

Dan Egan, the city's manager of cycling and infrastructure programs, said the event's popularity continues to surge.

 "The number of cyclists on the street, they've gone up every year the last 10 to 15 years so that's the measure of success," he told CBC News. "We have a big challenge in this city because the streets are so narrow."

Bike To Work day is the unofficial kickoff of Bike Month, which runs to late June with a series of events.
