Virtual 26x1 mile leg.
Even at 9:30pm I wasn't the only one on the track, but the older couple walking moved outside the fence and everyone else was keeping decent distance, so I dropped the mask to breathe freely.
~2:35 at halfway, and that 3rd quarter sucked. Put everything I had into the last 400 and was sucking wind for awhile after I finished.
I miss taking sub-5's for granted.
Dunno if this is progress from the 5:23 since I skipped the mask, my left leg was a little sore during the warmup, but I don't know how much that impacted the run.
