I shot for 20 miles today, with a view to that being the longest long run of the marathon training, and fucking missed it.

I don't know what the issue was really, everything was fine until about 14 miles in and at that point it's like a switch flicked off somewhere inside me and I knew it wasn't happening. I didn't have to stop or anything but I was just running on empty all of a sudden. It was weird. Managed to rally and get another couple of miles back to my house to make it 16, but that was it. Maybe I should have just headed off in the other direction. Once you've seen the house that's it, isn't it? You're not going to go "I'll just bash another another 4 miles out even though I feel absolutely spent" when the front door is right fucking there.

17 miles felt relatively easy a couple of weeks ago too, so it was very disappointing. I was really pissed off afterwards, had a right sulk about it! I can't remember the last time, running wise, I really failed to meet some sort of a goal I wanted, so it feels like a big setback. The marathon is 4 weeks on Sunday, so there's time yet I guess. I had run 10 miles a couple of days ago, but that's nothing unusual. Maybe tone the distance down with a couple of shorter ones though and go for it again next week.

@Henry, coach me or something. Tell me it's all going to be fine.
