Rebuilding, rebuilding, rebuilding

Feels like starting rebuilding over and over again. I caught some fever maybe one month ago which took the best feel out of running. Tried then Kurren Kierros 10K in Kauniainen right after and managed to do 37.02 (17.40 and 19.22 per 5K) which is probably the slowest 10K I have ever recorded in a competition. It felt really weak. Today went for 3 x 2K in home stretch to clock in 6.43, 6.51 and 6.54. Stronger than Kauniainen but overall painfully slow compared to where I’m coming from. Couldn’t even cut the fourth one. Basically no visible progress over the past two months. I guess the straightforward recipe is to start collecting some serious mileage again.
