walking: a wee change in plans

I'll be doing a 15K-step walk tonight, but I won't be moving to a MWF schedule quite yet: my right foot got achier on Sunday, and it's still somewhat achy, so I don't think I'm as ready as I'd thought I was to move to a three-times-per-week walking schedule. So I'm upping the step count to 15K steps per walk, but I'm keeping the frequency of walks at twice per week.
