You should deffo see your GP. After all you need lungs and heart to live, so this could be an early sign of something that is really important to have treated. As you know a few unlucky folk do get heart problems despite a healthy lifestyle, so a little bit of caution can really pay off. Good luck...
. Does anyone have any ideas or has anyone experienced this? I'm wondering if I should see my Doc, however I'd feel pretty stupid asking about a fitness issue when I otherwise feel fine.
I did a perfectly good marathon in Rotterdam, the week after I did several normal easy runs, but by day 6 I barely managed to run 2 miles to my local parkrun. By day 8 after the marathon I was out of breath walking to the train station.
There is a variety of what it could be, might not even be the same thing. So rather than giving scare stories I just tell you to get it checked out.
RR - would it be worth it if you do the charity contribution an dove up to pen CC ? That is what Lindsey Parry recommends to people these days.
A friend who ran it a few times says it is helpful to be sub 4 so to get ahead of the green start. Not sure how much difference it makes.
Ran Rotterdam last week, did run/walk testing, but hit the run too hard again. Blew up at km 37 and ended up 3:42, only 2 minutes of my PB. Good conditions but really windy, last 5k into the wind, so blow up was probably mostly in the mind.
