To think there is no way my SIL will manage to run the marathon?

This will probably make me sound like a horrid unsupportive cow, which I'm not, honest!
We were all hugely surprised yesterday when SIL revealed that she has secured a charity London Marathon place. She currently does zero exercise, refuses to walk anything other than short distances as she finds it too much hard work, and is fairly unhealthy generally. She hasn't done any kind of running / jogging for over 20yrs (and never a marathon)
It is obviously fantastic that she wants to start training, and has a goal to aim for. But to go from zero to 26 miles in 4 months is madness, is it not?
I'm a huge lazy glutton right now. I have run a few half marathons over the last few years and I think I could probably get round a half marathon course by the end of April if I started training next week. But not a whole marathon.
AIBU to think that a very unfit person who does not exercise in any way at all can successfully train for a marathon in just over 4 months?

I went from ZERO running experience, 19 stone fatty to half marathon in 9 weeks. I completed it in 2:43:41. I certainly wouldn't recommend it, but I'm bloody proud of it.

Although I suspect she will drop out when she realises how far a mile is when your running, let alone 26!!!!

Please update us as to progress op as time goes on @edsheeransgingerbeard

I would suggest you both register, print barcodes and do a free parkrun this Saturday.

@edsheeransgingerbeard did you go to parkrun?

@christmasstress how did you manage that?? I'm not running at the moment & would love to be to achieve half of that!

God knows @NYnachos - it's a mystery to me!!!!
