In reply to Wainers44:
I had my vaccination yesterday at about the same time as you.
I too have not had any reaction around the site of injection.
I had to trail to Leicester (about 30 miles away), so stopped off at Slawston Bridge on the way back, and did some traversing/bouldering on the defunct railway structure. This was a better performance than anticipated, having done no climbing of late (obviously).
Today I went for a 10Km run at Rutland water which I thought that I might have been faster with, but was about the same as usual. (My problem sometimes is that I lapse into a running reverie as I think about other things, and forget to try to push the pace at different parts of the course).
I too was a little drousy, but this is much more likely to be due to not drinking enough water soon enough, and of over doing the volume of food eaten for my very late lunch/tea.
Lots of walkers, and to a lesser extent bikers at Rutland Water, but at least the ground is getting better currently due to a drier phase for a couple of weeks. So less mud.
