Boston Marathon pacing strategy

Start conservative despite downhill opening. Save energy for Newton Hills (miles 16-21), then use the final downhill miles to close strong.

Pacing by course segment (miles)

1-5DownhillResist the temptation to bank time. Run 10-15 sec/mile slower than goal pace.
6-10RollingSettle into goal pace. Stay relaxed through Framingham and Natick.
11-15Flat to rollingMaintain rhythm. Wellesley College crowds will energize you at mile 13.
16-20Newton HillsRun by effort, not pace. Expect to slow 15-30 sec/mile. This is where races are lost.
20-21Heartbreak HillStay mentally strong. Shorten stride, maintain cadence. Don't surge at the top.
22-26DownhillLet gravity help. Pick up pace gradually. Trust your training.

Fueling notes

Take an extra gel at mile 15-16 before Newton Hills. The climbs increase energy demand significantly. Consider salt tabs if racing in warmer conditions.

Race-day tips

Frequently asked questions

How hilly is the Boston Marathon?

Boston has 156m (512ft) of elevation gain, with the famous Newton Hills from miles 16-21 including Heartbreak Hill. Despite being net downhill (140m drop), the late hills make it challenging.

Is Boston Marathon good for a PR?

Boston is harder than flat courses like Chicago or Berlin due to the Newton Hills coming when you're already fatigued. Most runners find it 2-5 minutes slower than their flat marathon potential.

What is Heartbreak Hill?

Heartbreak Hill is the fourth and final hill in the Newton Hills section, located between miles 20-21. It rises about 27m (88ft) over 0.4 miles. The name comes from the 1936 race when Johnny Kelley's heart was 'broken' after being passed here.

What pace should I run at Boston?

Start 10-15 seconds per mile slower than goal pace for the first 5 miles. The downhill start tempts fast early splits that you'll pay for on the Newton Hills.
