achilles tendonitis and scar tissue

Sounds like you are training your aerobic system for one side of the equation only (to support the output,but not to recover from it). But this may well be a different discussion altogether!

The hard thing with endurance running - is your fitness improves sooo much quicker than anything else. (does for me) and my legs lag behind a long way. Trying to find that right balance between volume (for fitness) and Recovery (for muscle feedback) is harder than it seems.

Sprinting from a coaching standpoint visually is much easier. You’re in the one area. Distance runs could be a 20km run!
