If I run today, it will be a slow, tedious 60 minutes where my muscles will feel painful and I'll be risking injury.
Yesterday, went for 95 minutes, hard at times, never conversation pace.
Does trotting along today really have any benefit?
If you are really on the edge of not running today, just go out for 30 minutes rather than 60 and get blood moving through your muscles. Don't worry about pace, and if you are feeling better as you go you can increase your time (assuming that you have on your 'schedule' 60min). My guess is you will feel better running tomorrow if you do 30 today and not 0. I believe with increased bloodflow to the muscles they will heal quicker since the blood carries what is needed.
