Our expert says:
I remember answering your question because in my reply I mentioned that I have run one fewer Comrades than you have!
If you can run 10 km in 48 min, ie less than 5 min per kilometer, and you can run up to 32 km at a stretch, it is highly unlikely that you have myocarditis. In addition, almost all patients with myocarditis have an abnormal resting ECG. The diagnosis is therefore very unlikely.
Much more likely is that your fatigue is non-specific and possibly due to a combination of factors including life stresses.
The diagnosis of myocarditis is also a serious diagnosis which should be made by a cardiologist. If you arestill worried that you may have myocarditis then I would arrange to see a cardiologist for tests including an echocardiogram. At the very least you need peace of mind. Also, it would be a great shame to stop you running if you do not have myocarditis. For this reason alone it is worth seeing a cardiologist.
Best wishes. JT.
