Great Manchester Run
Race Day Weather
Comfortable temps, chance of rain
Mild 51°F temps at gun time mean comfortable early miles without overheating risk. Temperatures rising to 60°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing. There's a chance of rain, so have a backup gear plan ready. Moderate humidity at 73% is worth noting for effort level, especially in later miles.

Race Info
The Great Manchester Run is a 10K and half marathon held each May in Manchester city centre. Both races start on Portland Street; the 10K passes Old Trafford, Trafford Park, and the Coronation Street set before finishing on Deansgate near Beetham Tower. The half marathon, added in 2017, extends the route east to Manchester City's Etihad Stadium before rejoining the 10K course to the same Deansgate finish. The 2026 edition drew a record 38,000 runners.
