How much are you running (time wise)?I'm doing strength 6 days a week alternating between upper body and lower body. I'm also running 5 days a week. My speed is finally coming back slowly. I'm at 730 pace, bot sure I can get quicker without injury.
At what point is my running depleting my muscle gainz?
Sprints will enhance your gains. Limiting runs to 30 minutes will minimize the catabolic price.
