Resuming training after GNR

Hi, I did the GNR last weekend and although I didn't get under 2 hours as I had hoped I was still pleased (I ran with my husband and did it in 2.10)and am already looking forward to trying another half marathon to get under 2 hours. I was on holiday last week, but did do 3 easy runs. However today back to work (although I am stay at home mum, but you know what I mean), all motivation has gone, I really enjoyed the level of training that I was doing for the GNR, but I think this would be too much to continue with or is it? I have identified a half marathon in February, but between now and then there does not seem to be many about (I live in Aberdeen, but travel to Lancashire a lot so can do races there.

Does anyone else feel like this? Incidentally I was exactly the same after my very first 10k, and of course the solution is to plan for another one, but there does not seem to be any in sight. Maybe I should have another week off to think about it?! Help anyone?!
