Phew, that was a struggle. I was going to run yesterday, but I had a breast lump scare and had to go to the Churchill Hospital, Oxford for scans (it turned out to be fine), and we were late getting home.
Anyway, I was knackered today and it was just one of those runs that was a struggle from start to finish, and I thought 5k would never arrive! My inhaler ran out mid week and I haven't been able to pick up a refill yet, so my breathing wasn't great for the first half of the run, and I could have done with more sleep. One surprise though, it was very frosty ( -2 feels like -4 apparently), and if I had known the pavements were so icy i would have stayed at home, and consequently was going what I thought was super slowly so as not to slip, so was surprised when I looked at the run stats to see that it was actually faster than the previous run.
I also had a very nasty and persuasive gremlin muttering darkly all the way round: what do you want to go out there for when it's nice and warm in here?; nobody can expect you to run today when you could do with another hour's sleep; look at that frost, I should turn round and go home; you can't expect to run very far at your age, take up macrame instead; look at that slope, you'll never run up that; you've done 3k, that's enough for today; you're just not up to this 5-10k lark.
Isn't it strange that you can struggle and force yourself to do something like today's run, can't wait for it to end, yet you come back and the high hits you and you can't wait to do it again.
