Nah I haven’t gone crazy.
The way I see it, I’m pretty sure that my legs aren’t smart enough to know exactly how many kilometers they cover each time I run.
What they do remember however is what LENGTH of time they have run for and at what INTENSITY.
Take the #OneWeekOneAustralia running project I completed back in May.
I ran 145km in 7 days. No big deal right? Wrong!
Look at it this way instead. 25hrs of running over 7 days.
Put into running numbers… even if I ran these 25hrs at 5 minutes per km which is a pretty casual jog for myself. I would have run 300km+.
Now the legs are taking notice!
But 72km of that running was logged uphill an intensity very close to what I would aim to race at. I’m not in 30min 10k shape at the moment, but not too far off either.
So it’s safe to say that a lot of that 72km uphill I was pushing at a better speed than 5min/km intensity. Where’s that leave the estimated km’s? Who cares!
The point is the body doesn’t know how many kilometers it ran. Just that it ran for ‘X duration’ at ‘X intensity’ over that terrain at the fitness level I was on the day.
Food for thought
If you are running set distance intervals for example repetition 1kms, as you become fitter you would run each 1km faster, therefore, legs are running for a shorter duration at the same intensity as you progress week to week your training. Total load is being reduced.
Would the legs benefit more by running for TIME instead of DISTANCE?
These days the more I’ve been training off road the more this theory is true. Take yesterday here in Queenstown NZ. I ran for 60mins but only covered 10km. But my legs are throbbing this morning. Why? Steep uphill. The distance tells a very limited story.
Agree or disagree?
