Week 3 / 20
how fantastically well the Half Marathon went, but I thought I would include some graphs showing how much below my theoretically optimum heart rate I ran most of the race. What is particularly striking is that there is no "heart rate drift," that is to say, once I hit about 170bpm, my heart rate rose no higher until the final sprint. I'm guessing that this is partly due to the cold conditions - around 5 degrees - but I am more and more convinced that this is a measure of my efficiency, both cardiovascularly and in running technique. Also, my pace was relatively even - or at least I didn't slow down much in the second half. The first half was run at an average pace of 3:57min/km while the second half was run at 3:58min/km. As far as aches and pains go, I'm feeling fine, just got a bit of a snuffly cold that I haven't been able to completely shake off for a couple of weeks now.
