New PB
To run a marathon one must learn to never give up.
If you are losing the game, then change the rules.
... Such are the ways of the toast.
I have returned to running and after thoughts on the advise given to me, have chosen my own path to the dark side. So far the calf holds firm, and I set a new PB this morning. My heart rate was average at 138 for 13-ish km. That's down from 139 for 10 km on Sunday. My 29 km easily cruised around 155. I'm enjoying the slow and it feels good.
