Weekly Mileage Reaches 100km

After 1 year barefoot running, slowly my weekly mileage increased to over 100km. Last week I completed 101.2km. And it was not achieved at the cost of next day training.

To achieve this, I have been made myself comfortable with 7 runs per week without rest since this August. There should be no speed works until I made myself adapt to the training style. Every run was aerobic (under MAF heart rate) so that stress was minimized. And there turns out to be large stress cushions under such training loading. That is, may MAF pace improvement stopped around 6min/km; and even when I violated 10% rule, increase weekly mileage from 60k to 100k, I still stayed injury free and even without DOMS after 34km long run. After all, I found it goo way the increase weekly mileage while staying injury free. And by this I could increase my yearly mileage to over 4000km. The only thing I need to figure out is how and when to incorporate speed/hill workouts in it, let me do with cautious and stick on 10% rule.
