24.28 at parkrun yesterday, my slowest since the very first parkrun I did, just over two years ago - although to be fair I had run 9km to the start at not much slower pace...
I also ran home afterwards, a more direct route, so only 7km, but a lot of it uphill (including one climb that was over 10% at its steepest part). I wish I'd paced myself a bit better on the outward leg and parkrun itself because I suffered badly and it took close to 50 minutes. It didn't help that the early warm sunshine had by then given way to a chilly headwind and stinging rain. I also think I was a bit dehydrated by then.
So, 21km overall, in a tad over 2hrs. Not bad but even allowing for the lack of recent running + terrain + conditions, I'm going to have to put in a hell of a lot of work between now and September to have any hope of a sub-3.30 marathon.
