I guess we won’t die or cause damage from doing ultramarathons or High Intensity Interval Training.

It just feels like we will. 🙂

Do stay hydrated, don’t overheat and if doing a marathon, give your body two days to recover, though.

And dont freak out about puking or seeing puke on the marathon course. Its a common occurrence.

That study makes perfect sense to me - those cardiac blood markers are a secondary response to high heart activity.

So if you were just sitting on the couch and had those indicators it meant your heart suddenly went into overdrive for some reason and you’re gonna have a bad day.

But if you just ran a marathon - perfectly normal.

But it WILL mean that those who just ran a marathon and are having cardiac problems can’t be diagnosed from those markers.

My ultramarathon is walking around the cul de sac.

I am in awe of people who can run a marathon.

BTW, you probably know the origin of the race-—the Greek runner Phidipides was sent by the Greek General Miltiades after the battle of Marathon to, as the story goes, tell the Athenians the good news. Traditionally it’s held that he ran 26 miles. But many scholars think ol Phid ran to EVERY Greek town along the way before he got to Athens!

No wonder his heart exploded when he arrived to yell “Rejoice! We conquer!”

Interesting. Thanks!

I’ll drive.

I did an ultra marathon once watching Centennial, Lonesome Dove, The Ring Trilogy and The Hobbit with no change in cardio markers. However it did take two days to get my rear in gear again.

Next year, I will celebrate my 50th birthday by running a 50 miler.

I am not a runner, I am built like a thumb but if you can run 3 miles, you can run 50.
