~5.6 miles @ ~23.9 min/mi

"Where's that echo coming from?" Dr Mary asks, as Runkeeper's GPS voice reverberates. Our walkabout is passing near Lake Fairfax Park's soccer fields, and what we hear are offset time-and-distance announcements from my phone and then hers. Half an hour ago we hit the "Start" buttons slightly out of sync. Oops!

A cool morning makes for pleasant hiking along shaded horse trails. Polite mountain bikers swoop past and splash through Colvin Run and its tributary creeks. Mary reminisces about long-ago Fairfax County Trail adventures here; I recollect a painful introduction to snowshoeing under her supervision (on 12 Feb 2010; see Snowshoe_Shin_Bruise). Conversation is splendid and wide-ranging.

Missed turns on the return trip add a bonus mile and offer opportunities to bushwhack, clamber over deadfalls, tiptoe across shallow streams, scout for trails past an apartment complex, and descend steep rooty-rocky slopes. And It's All Good!
