THE QUESTION THAT haunts runners after a race-good or bad, personal best or worst-is, Could I have gone faster? Even after Molly Seidel finished third in the 2020 Olympic Marathon, fans wondered if she could have chased down Brigid Kosgei of Kenya for the silver. After all, Kosgei finished just 10 seconds ahead in 2:27:36. The answer might be found on Seidel's Strava, where she posted an unofficial summary of her race in Sapporo. According to the heart-rate data captured by Seidel's Coros Apex watch, it doesn't look like she could have pushed much harder for those last few miles. Her heart rate soared past 180 bpm, holding steady at her near maximum right until she crossed the line. In theory, Seidel was firing on all cylinders.
