Running

I'm not trying to add the speed work, it's more I'm (mildly) worried about the impact of not being able to keep it slow enough because my pace keeps creeping up. but as I say the point is cumulative fatigue which means I'll not be going out as hard on days after the more strenuous workouts.

in other news, a dirty contact point on my fr620 meant it wouldn't charge/sync so the batt almost fully discharged and wouldn't stay on, so I wiped it thinking it was fucked before I realised it was the contact points, got it recharged but now have to setup everything again on the watch. ffs. luckily didn't have any workouts on there I hadn't uploaded.

If you've got the pacings wrong for you/your target time that's a different matter, but come marathon day you will be capable of blasting through the first 10k far quicker than you are now and will be planning to go, running painfully slowly will have the benefit of teaching you to hold yourself back for the first 20k when you're feeling fresh, changing your plan based on not having seen the result yet seems a bit premature, especially when you've been complaining of multiple niggles already...
