To borrow the language of powerlifting, I was grinding this one out....
(My main physical complaint was the tight sore lower back, right hand side; my main mental complaint was that yet again I have left ALL my work for Sunday night, ugh!)
Anyway had to make a few deals with myself in order to get this one done. On the bright side, the weather turned surprisingly nice: 60ish, sunny, after some days of really wintry rainy weather.
Schedule asked for 90min with 30s faster every 5min - I did an approximation as follows:
First hour as 12 x (4:00 jog, :30 fast, :30 walk)
:20 as 4 x (3:30 jog, :30 fast, 1:00 walk)
