With the time constraint of a 45 min slot I figured I needed high intensity. Decided on 2 sets of 5kms increasing speed as follows: 1km @4.30s, 2-3km @3.40s and 4-5km @3.30s.
First one was fine with HR only hitting 160 but for the second one I was gawwwnski at 4.5kms with my HR hitting 170. It is noticeable that even with a [5] min recovery the HR was quick to increase on the second set. It goes to show that once you hit the red zone there is no turning back. Had to call it a day there.
Unusually for me I felt horrid for the rest of the day whereas the endorphins usually make me sail through the afternoon.
Have decided to run into work in the morning. Company most welcome.
