Toronto Marathon
Toronto Marathon is a rolling marathon in Toronto, Canada, held each May. Point-to-point and net downhill from Mel Lastman Square down Yonge Street to the lakeshore, with rolling hills early and a near-flat second half. Early-May mornings, typically cool, around 6-14C. With Toronto Marathon's constant undulation, pace by effort rather than the watch: even effort beats even splits here.
