I completed the C25K programme last year, and absolutely loved it!! I actually enjoyed the running itself, and couldn't believe the progress I was making. I've recently started again, after a few months ofF (life got in the way) and I'm loving it again. It's so much easier second time around!
My question is this - both last year and this year I've done almost all my running after work, in the early evening, and I've been absolutely fine. But on a few occasions I've been out in the morning or at lunchtime, and I've noticed that whenever I do this I get a splitting headache, which lays me up totally for the rest of the day - drugs don't seem to get near it, and I just have to go to bed. It's always right behind my right eye, and accompanied by a slightly sicky feeling in my stomach.
What's really confusing me is that it always comes on within a couple of hours of finishing the run, regardless of whether I go back to work or it's the weekend and I'm just at home for the day. But it never seems to be a problem when I run in the evening, even though I'm up and about for a good 3 - 4 hours after running.
I thought it was about dehydration, but I don't think that can be it - it happened yesterday after a lunchtime run and I'd made a conscious effort to drink plenty of fluids all morning, during the run, and through the afternoon. It made no difference at all. I also made sure I had a banana immediately before running (so my stomach was empty enought o be comfortable, but with 'fuel' there), and a big bowl of soup afterwards.
Can anyone help?? I could just never run at any time other than in the evening, but that isn't really practical, and is very limiting. I quite often have other things on at that time.
Also, I'd just love to understand what's going on!
Thanks very much
