Get in the drops and give me 2x20!

A favourite of the training with power brigade is the 2x20. Basically two - twenty minute intervals at your functional threshold.

The first one usually is fairly easily. The second one introduces pain that you typically dont usually inflict unless in a race situation. If the second interval is easy - then you FTP estimate is too low!

Pretty happy with my effort this morning, I also wore a heart rate monitor to give myself some feedback on my HR pacing from my last Calga TT, my HR hovered around 170-175bpm throughout the intervals which means my pacing was pretty much spot on ~ 300w average.

What was also very interesting was my cadence, i averaged 89rpm, which is identical to my Calga TT cadence. I wasn't focussed on maintaining a particular cadence so find it interesting that I gravitate towards this number.. Have to think about that a little more in future...
