I can say that I'm starting to feel good again. O-ringen was a highpoint physically but a low point technically. Afterwards, I got sick and wasn't able to run hard for the next two weeks. I did some good technique sessions at a training camp in Italy, so I had some technical improvements but physically a down point. But the last training week has been good so the physical side is beginning to come around.
O-ringen is a lot of fun, but it seems to be a good way to get sick.
Another certain 'getting-sick event' is Tiomila. Staying up all night watching the competition doesn't match to well with serious training and racing the week after...
