Oslo Marathon
Race Day Weather
Comfortable temps
Mild 53°F temps at gun time mean comfortable early miles without overheating risk. Temperatures rising to 63°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing. Moderate humidity at 75% is worth noting for effort level, especially in later miles.
