Massie Street Hill Loop/Magnolia Street Loop

I walked and jogged the Massie Street Hill Loop this morning in 26:10. This loop, I believe, would make an excellent base for interval work. The smaller loop within, bordered by West, Massie, and 47th Streets, is nearly half a mile around according to my Camry, or exactly 874 yards according to Google Earth (880 yards is half a mile). I did that loop three times today, so obviously my treks to and from it total a half mile. What I'm unsure of is whether running and walking it multiple times will aid my pursuit of trail-race improvement (or, of course, whether that pursuit will endure long enough to justify the writing of the greater part of this paragraph). We'll see.

This evening I walked and jogged the Magnolia Street Loop in 27:07.
