Thursday - 16 km with middle 20’ at threshold

It was a disgustingly steamy overcast morning, far from ideal conditions for my weekly threshold run. No other starters today, I set off from the stone arch at North Head at 6:15 am for my easy lap before jumping straight into the the 20 minute effort. Just like last Thursday, I simply focused on breathing correctly while keeping my eye on the heart rate throughout. I was very surprised to finish with 5.95 km holding 3:22’s at 169 bpm, much faster than I had anticipated in that humidity. I grinded through the remaining 5 km for 16 km all up.
