I read somewhere (trans: I can't find the reference) that the majority of post-mortems of London Marathon fatalities show congenital heart defects that simply had never been diagnosed (mainly because there was no reason to go looking for them).
If you're young (14-35) and want to get checked out then try: http://www.c-r-y.org.uk/ for a screening (I had one about 4 or 5 years ago - and got the all clear - as Mrs GB was worried about the amount of long distance riding I was doing).
Based on 23 years’ experience, the approximate overall risks of running the Marathon are:
contact with St John: 1 in 6;
contact with a hospital accident and emergency department: 1 in 800;
hospital admission: 1 in 10,000;
death: 1 in 67,414 – a risk which is comparable to many daily activities.
