Been doing Recumbent bike and some walking.
On the recumbent, up to 4 miles without wincing every time my knee bends!!
Walking: sigh….. Up to 1.5 miles at a 21 minute pace. Walking is harder and apparently uses some
lazy muscles much more than the recumbent, because i had a number of whiny muscles while walking today.

But i think i will be able to meet my goal for my first post surgery half marathon in November.
10 months away, i should be able to do this. I plan on walking the whole thing, no more running.
But still looking forward to meeting my goal!
