I've been telling myself how good I feel about my marathon training. I'm doing well. Much better than I did in 2015. I feel better. There's no need to worry about the wheels coming off like they did back then.
So just to prove this to myself, I plotted my weekly distance (yellow line) against what it was in 2015 (blue line) as well as the week's longest run (yellow dotted line) against what that was in 2015 (blue dotted line). Marathon week is at the right edge of the graph, and the start of the training period at the left edge; so comparisons are between"weeks to go" rather than "weeks since start".
What does the graph show? Well it shows quite clearly that in 2015 I was also doing great, running well, everything smooth until 11 weeks before race day when I had a bad week, followed by two weeks where I tried to catch up, followed by 3 really bad ones. And boy do I remember those bad ones! And it - worryingly - shows that I am currently in week 12 before race day. So pretty much at the same point of the journey where it all fell apart 18 months ago.
Of course that's not going to happen. Absolutely not. But I am *very* conscious of every twitch and ache and trying to be super careful. I do not want history to repeat itself!
