Have you ever wondered what? really it feels like it win a major championship? Most of us will never experience it – but we can take a look at the physiology behind the ups and downs of a big Sunday thanks to data provided by Whoop, the wearable fitness tracker endorsed by Rory McIlroy.
On Monday, Whoop broke down McIlroy’s numbers from the final round of the Masters, and one factor stood out above all else: his composure under pressure.
When McIlroy took a two-shot lead on the final hole, his heartbeat told a compelling story. According to Whoop, McIlroy’s resting heart rate is in the 47 to 49 beats per minute range, but after his suspension. tee shot in the fairway right trees on 18, his rate rose to 135 BPM—a normal response in a high-stakes moment. But McIlroy quickly regained control. By the time he went into his second stroke, his heart rate had dropped to 121 BPM.
After McIlroy hit his approach into the front bunker, his heart rate rose again to 136 BPM, but he again quickly calmed down. At the same time, McIlroy’s heart rate dropped to 117 BPM before falling to BPM after his winning drive.
The data points to a striking conclusion: at moments when most players tense up or accelerate, McIlroy did the opposite—he slowed himself down.

The most disastrous Masters Sunday blowout was never televised
James Colgan
McIlroy displayed the same pattern of composure and control throughout the tournament. His recovery scores remained consistently high – 87% on Sunday, peaking at 94% – signaling his body remained primed. His effort reached 16.8, reflecting continuous effort without fatigue.
Sleep, often neglected, gave him an advantage. He logged over 9 hours on Saturday night to Sunday (92% sleep performance) and averaged 8.5 hours over the weekend. His resting heart rate remained remarkably steady, between 47-49 BPM—proof that his elite conditioning and recovery was paying off.
And the workload was no joke: more than 24,000 steps on Sunday alone and more than 91,000 across the four rounds.
Getting food? McIlroy has learned to stay under pressure. In his most intense moments, he doesn’t let the adrenaline take over—he reins it in and takes back control. In the end, that calm can make all the difference.
