Time for another bash at the 2x20 minute session with an average HR of 160+
Managed to get through the session but it wasn't pretty. The last 75% of the 1st effort was done at a power output of 300W and the 2nd at 260W so at least I got through it.
Quite pleased that at least I had a bash at it and hopefully when I come back from my holiday I'll feel more enthusiastic about things again.
Boat here I come...
