Great 4 x 2K

Just came from home route: 6.28, 6.28, 6.33, 6.30. First two 1 min, last one 2 min break. Felt from the start that it was going to be huge. The other day on Otaniemi 3 x 1500m completely opposite feeling: 5.00, 4.59, 5.02 and decided to walk away. I felt so tired. Today I had a better night behind and felt energized. Next tuesday there will be 10 000m in Otaniemi.
