There is absolutely nothing wrong with wanting to do the London Marathon.
I've just entered the ballot for the 6th time this year. Not expecting to get in though, but still hope I do.
I have ran the Yorkshire marathon twice and have entered for the new Leeds one next year which will be my 3rd. I am so excited now to do it, but know that I will regret my decision at some points during my training. The marathon is the easy part, the training however is not. Long long long runs with (what feels like) very little reward. No atmosphere, no medal. Just long hours putting into it. However, that finish line feeling is just the best and it is so worth it.
Before I entered the first marathon I asked for advice on here. I wanted to know the good and bad bits. The only bit I remember is that no matter what the maths say, you are not half way until 20 miles in.
IME a marathon is not two halves. It is a whole different experience. A good one (mostly)
I understand what PP's have said about London being pushy and too crowded. I've done GNR 5 times so I imagine the crowds are similar, but that means so will be the atmosphere. I think.
I think I will end up doing it through my running club. We have a queue. It might take me a few years, but I'll get there before I'm 50. I have no intention of a charity place. The cheapest place I have seen was £1500. I'd be lucky if I got 15 quid. Also GFA place!! HA!!! no chance. I'm not slow, but certainly way off the GFA place. Anyone who says that you can get one doesn't understand what is like to be a regular or slower runner.
