Thu 7/8 - PM 90 minutes plus 20 minutes in Walden

Temp and dew point each a few degrees lower than yesterday, every bit helps but still less than comfortable out there. Energy levels at low ebb, ran out of gas around the hour mark and shuffled in from there. Really, really tired. Also, somehow tweaked my left hamstring/TFL, probably just from all the uneven footing lately as I don't remember any specific moment when I might have strained the area.
