3/3: 30 minutes treadmill, hill interval - 9% at 3mph. After 15 minutes I bumped the incline down to 7% because I was using only the outside of my right foot and gripping the machine to avoid using the full right foot. 9% was just too much for the rear of the arch of that foot - I hurt it last Oct/Nov in a pair of new shoes with different arch support.

25 minutes recumbent bike - interval, rest: 1 minutes level 5, followed by 30 seconds level 10. By the end, my right foot was nearly numb.

This is not boding well for cardio ...
