Progressive run with father

Yesteday I rested. This morning was up at 5:30 a.m. and was out with my father to the conservatory at 6:20 a.m. This time I decided to run in his direction and with him in the first half of the run, I was feeling tight and sloppy, but just before the half way point I threw a huge surged and never looked back, never saw my father again till We were here in the house when I finish stretching, the second half was at a good pace, sometimes I threw surges and sometimes I slowed down, just enjoyed the moment. Did 8.5k without a watch, and I am really enjoyed training by effort these days. Have a great rest of Saturday!
