Well I am not quite sure on the wishing more people were like this but I do find the article interesting.
I am 7 months pregnant and have run three marathon as well as numerous half marathons, duathlons 10k races etc. I was very active before pregnancy and have of course reduced since.
Running a marathon is bloody hard work, extremely exhausting and you have to be fit for it. It a massive strain on the legs doing all the miles of training. Personally I couldn't contemplate it whilst pregnant and as I said I am extremely active normally.
I think just as surprising is the fact that she has time to train for a marathon when she has 4 children. Marathon training, those 4-5 months before are hard work. Every weekend you can pretty much write one day off for doing much else as you have to spend 4 hours going running. You need a very understanding partner or husband at the best of times, let alone when you have 4 kids!
But good on this woman I say and good luck to any other pregnant runners out there wanting to race still
