Toronto wants to avoid repeated traffic tie-ups from the two fall marathons running only three weeks apart, but whether either race will voluntarily move to a new date is a big question.

Even before last weekend’s marathon again left frustrated motorists in a downtown-wide gridlock, the city failed to persuade organizers to schedule one marathon in the spring and one in the fall.

“We haven’t had too much success in getting one of them moved to the spring,” said Peter Noehammer, transportation director for the Toronto and East York district.

The city has been getting an earful over the duelling marathons. “In the last few years, they’ve been drifting closer together,” Noehammer said. “We’ve had a number of concerns from motorists.”

The city has the power to simply cancel one of the events, but that would require a decision from city council, he said.
