I’m an ultra runner, I’ll do 50-60 mpw weeks during peak weeks with strength training.

I take 10g creatine, it did wonders for me. More energy and mental sharpness.

Strength training is essential for runners to avoid injury at high mileage. Sleep, strength, and nutrition. It can’t be ignored or you will get injured.

Some folks mention cutting it out to lose weight but at higher mileage I find it hard to keep on weight anyway.
