Sometimes I get on a kick with one particular workout. At the moment it is this one:

Watts are yellow and heart rate is in red.
This is four sets of 5 X 1 minute repeats. Today the goal was to keep my watts over 300 for every rep until I either made it to the end or blew up. Today was a good day as I made it right to the 20th rep before I faded below 300 watts. This is the first time I have made it this far so a good day out.
One of my major goals this winter is to make my legs stronger and this workout certainly taxes them. They are pretty tired right now, but a good tired.
