St. Lawrence Marathon
Race Day Weather
Cool conditions, tailwind advantage
Runners will face a steady temperature increase from 40°F at the start to 54°F by the finish, with average humidity at 54%. A light tailwind will assist runners throughout most of the course, particularly beneficial from miles 1-13 and 16-20. With no significant precipitation expected, it's an ideal day for pacing, but maintaining hydration will be key as temperatures rise.
