Boston Marathon

About the race

The oldest annual marathon and the one you have to qualify for. Point-to-point from Hopkinton over the Newton hills. Patriots' Day, third Monday in April.

Typical weather

April is spring racing weather: mild but unpredictable, with a real chance of wind, rain, or a surprise warm spell.

Who it favors

A flat road race rewards even pacing and threshold endurance. It is a fitness test with nowhere to hide, so the runner who resists going out too fast is usually the one who sets a personal best.

Go fast, know why
