Assefa ran Berlin's last 2K on a fully torn Achilles

Her manager says the tendon was completely gone over the closing two kilometers of a 2:11:04 win.

Tigst Assefa won the Berlin Marathon on a fully torn Achilles tendon and had surgery in Munich on Monday, CITIUS MAG reported, citing Agence France-Presse. Her manager, Gianni Demadonna, said she started feeling pain around 31K and that it escalated after 40K.

"The tendon was completely gone when she ran the last two kilometers," Demadonna told AFP. He expects her to miss about seven months of training before a long recovery.

Agent Dan Wighton said he spoke to Assefa's manager on the phone, who confirmed she ran the last two kilometers without an Achilles after a tear, and that she is doing well after surgery.

The splits show exactly where it went

Assefa was on world record pace deep into the race. At 40K she was projected to finish in 2:09:44, inside Ruth Chepngetich's 2:09:56. Then her stride broke down and she visibly limped over the closing mile.

Her last 2.2K took 8:04, more than 30 seconds per kilometer slower than any previous split in the race. She still won in 2:11:04, the third-fastest women's marathon in history and a new Berlin course record, as covered earlier. She now owns the third and fourth fastest performances ever, with her 2:11:53 from Berlin 2023.

Magness on how that is even possible

Steve Magness wrote a long thread on the pain science behind running two kilometers on a ruptured tendon. He points to neuroscientist Howard Fields and the motivation-decision model, the idea that the brain weighs pain against everything else you want at that moment and can turn it down with its own opioids when something bigger is at stake.

Magness says he lived a version of it. In 2014 he raced a half marathon as a tune up, felt his Achilles scream with about a mile to go, closed in 4:30 to win, and was out for months with a partial tear. His read on Berlin is not pure celebration.

"Real toughness is creating the space to take the right action," he wrote, arguing the same brain that let Assefa run on one leg is the one that can blind you. Magness says she was reported to be missing around six months of competing. Demadonna's number to AFP was roughly seven months of training. Either way, the fastest woman in Berlin history is off the road for most of a year.
