I recently found out I have a weak heart. I suspected it for a while but I finally found out for certain. I ran my first half marathon with a heart rate monitor and it turned out to be pretty alarming.
The common way for determining your maximum heart rate is to minus you age from 220. So technically my maximum heart rate should be 187 beats per minute (bpm). My heart rate was well below that for the first 15km or so, but then as I started to tire I noticed it started to increase. As I pushed on past the 17 km mark, I was at 185bpm.
By the 19 km mark I was well into the 190bpm zone and rising. The final 1 km was the hardest. I was tired but determined to keep up my pace, and so my heart rate went into the 200bpm zone. As I approached the finish line I was aiming to finish under 2 hours, which was my personal target, so I sprinted the last 300m or so. I felt fine, I felt I was pouring every ounce of energy into powering my legs to the finish. I made it across the line in 2h 00m 02!
So close, yet so far.
But here’s when I noticed that my heart rate had peaked at 205bpm and then I felt my heart pounding against my chest. It was alarming because it felt like it wanted to burst through and escape. It took close to an hour before it came down to my resting heart rate.
My housemate who also happens to be a cardiothoracic surgeon in the making said it’s never a good sign when your heart rate exceeds 200bpm. I brought it up with my running coach and he suggested a few exercises to build up my heart’s resilience.
I always though that saying you were heartbroken was just a metaphor, but maybe there’s more to it. My poor heart is so bruised and battered that it can’t even handle me doing the only thing that helps me escape.
The silver lining is that whilst I can’t do much about the emotional scaring, I can certainly do something about getting it physically stronger than it currently is. Here’s to hoping it works.
