Brisk-walked 6km in an hour today. It's slow, but I think it's a good start for someone who hasn't done any serious workouts in a long time. Thanks to Ze Bespren for the idea and motivation. I hope I can keep this up.
I'll be doing this again with her tomorrow if my legs will let me. They feel fine now, but experience has taught me that the pain will come the next day. So yeah, we'll see. And I'm going to keep this short for now because my body is screaming for sleep.
