Good on you for keeping up the training. Like you, I'm doing an autumn marathon (7th Sept) but have really struggled since Paris (7th April) managing only 10-15 miles per week.
I think my training was good (5 runs a week - easy, mid week long with some MP milreps speed reps, easy, then long run; alternate week hill reps) and netted PBs in half marathon (1:42 something) and 10 mile (76 something). Despite this I struggled from mile 19 of the marathon and finished in 4:02:18.
I did 6 decent long runs of 20-21 miles, pace around 9:40, and my coach suggested aiming for 3:45 in the marathon. Not sure if this is where it all went wrong, but I didn't get near it. Had a throat infection during taper which meant my last long run was 4 weeks out.
Apologies Roddie for hijacking your thread but yours & any other comments or thoughts are appreciated.
I'm currently using Prosport Factor 44 (comes in a range of factors) as I suffer from vitiligo and was beginning to find that the bits with no pigment were burning with P20. I like it as although it's thick it does soak into the sKin easily. I always felt that P20 was really oily on my face - could cope with it on my body.
I occasionally get migraine and if I do it's usually connected to a hard effort, either long run (in marathon training, possibly dehydration?) or maybe a speed session or race.
I get an aura, either can't focus on reading, or flashing lights & visual disturbance. Having spoken to the pharmacist I now take soluble aspirin at the first signs. This takes the edge off things quickly and avoids the subsequent banging headache (which feels like a monstrous hangover, intense pain whenever I move) which would usually last at least the rest of the day.

Obviously, the days are flexible, the idea being to have some rest between sessions. Also, don't worry about speed - I found when I started that I would try to run too fast when on my own without realising it. Just jog gently at a pace where you can breathe easily - that may not be much faster than a walk to start with, but we all start somewhere, and if you're sensible with it you'll keep going and see the benefits.
4:02:22 for me in Paris today. Not a PB, but my second fastest marathon. The underpasses got me (among other things). Found it really hard to get up the other side and then pick up the pace. Lots of great French support ('Allez Clare') as the names were on the numbers, and a couple of times when I started to walk I had Frenchmen who'd lived in Aberdeen come & chat to get me going again.
