What Is Heartbreak Hill?
ℹ️ What is Heartbreak Hill, and why does it matter so much?

Heartbreak Hill is the last of four Newton Hills on the Boston Marathon course, peaking at mile 20.5. It rises about 88 feet over half a mile — not steep by hiking standards, but devastating at marathon pace after 20 miles of running.

The name comes from the 1936 Boston Marathon, when defending champion Johnny Kelley patted leader Ellison ‘Tarzan’ Brown on the shoulder while passing him on the hill. Brown rallied, retook the lead, and won — breaking Kelley’s heart.

The defending champion arrives in Boston as the overwhelming favorite. His 2:04:15 course record from last year was run in less-than-ideal conditions — with a tailwind today, sub-2:04 is firmly in play.

Lead Change in Women’s Race
Hellen Obiri has surged past Amane Beriso to take the lead at mile 19. The two-time defending champion is making her move on the Newton Hills.

Lemma After the Finish
"
I knew at mile 20 that today was my day. When I hit Heartbreak Hill, I felt something I have never felt before — like the road was pulling me forward. This course, this city, it gives you something extra.

A Day for the Ages on Boylston Street

I’ve been covering Boston for over fifty years, and this one ranks among the very best. What Lemma did today wasn’t just fast — it was artful. He ran the Newton hills like a man who has studied every meter of this course, saving just enough for that devastating final surge.

The crowd knew they were watching something special. When he turned onto Boylston, the roar was unlike anything I’ve heard since the Duel in the Sun back in ’82.

Scenes From the Course: The Crowd Energy at Wellesley Is Unreal

The famous Wellesley Scream Tunnel is in full force today. The noise is absolutely deafening as the elite women pass through — you can hear the crowd from half a mile away. This is what makes Boston special.

Sisay Lemma has thrown down a devastating move on the final climb of Heartbreak Hill. He’s opened a gap of nearly 20 seconds on Chebet, who is visibly struggling. This is where Boston marathons are won and lost.

The Heartbreak Hill Factor: Why This Year’s Race Could Shatter Records

The westerly wind at the runners’ backs is a gift from the marathon gods today. Boston’s notoriously difficult point-to-point course — with its net downhill but punishing Newton hills — typically doesn’t produce the fastest times. But the tailwind changes the calculus entirely.

Lemma’s first half of 1:01:22 puts him right on the pace he ran when he set the course record of 2:02:57 last year. With conditions actually better today, we could see something special on Boylston Street.

The lead pack has been whittled down through the hills of Newton. Five men remain in contention at the half. The pace has been remarkably even.

Lead Pack Passes 5K in 14:18

A large lead pack of about 12 runners passes the 5K mark together. The pace is aggressive but controlled — right on 2:01 marathon pace. Sisay Lemma (Ethiopia), Evans Chebet (Kenya), and defending champion Benson Kipruto are all tucked in near the front.
