Hi Docs, a couple years ago I wanted to reduce my waist size and improve health by getting into running. So far I’ve had a blast and have managed to do two marathons.
Both marathons I have averaged about a 185 bpm. After my last marathon, someone on Strava commented that I really need to work to reduce my marathon heart rate and that I could be setting myself up for myocardial fibrosis or ventricular strains.
Is this really something I should be concerned by? I always assumed that running for long periods of time at high heart rate would just make my heart stronger than the average person, which should result in improved health outcomes.
