David Miller is loping along the Toronto shoreline in shorts and a singlet, passing the pavilion at Sunnyside as he heads east toward the city’s downtown, and talking about his decision not to run for re-election in 2010.

“I do feel freer,” says Miller. “It’s about having announced the decision. When you’ve made a significant decision like that, whatever it is, until you go through with it, it weighs on you.

“It does feel much lighter. My whole body feels lighter.”

And that’s a good thing when you’re 50 years old and running your first half-marathon — 13.1 miles or 21 kilometres — along Toronto’s waterfront.

Miller is in an unaccustomed position — decidedly in the middle of the pack, just one in a stream in a stream of heaving shoulders and striding legs, running shoes, shorts and ball-caps.
It’s not in David Miller’s nature to enter a race that he knows he can’t win.

Deputy Premier George Smitherman ran the five-kilometre route, arriving near old city hall feeling “fantastic.”

He ran the full marathon three years ago. “Coming up Bay Street today and feeling five-kilometre legs under me — not marathon legs — was particularly great,” he said.

Asked whether he plans to run for mayor of Toronto in next year’s election, Smitherman he’s been “very clear” that it’s a decision for 2010.

“That’s next year’s race,” he said.

While Miller and Smitherman were busy running, Toronto Coun. Georgio Mammoliti was sending a strong signal that he intends to be part of next year’s mayoral race.
