My training is low mileage. It implements periodisation, blocks and some recovery.
It is low mileage and gets a bit higher mileage at times.
I cycle continuously:
3 - 4 hard workouts a week on normal weeks
8 hard workouts on hard weeks
I start with 20' at 89% - 92% mhr this pace feels okay. I am still under second ventilatory threshold. I experience that if i go over that in intervals or continuous runs i get those naggin pains. Stiff muscles and just am worn out.
Heart rate drops for certain for the pace i do those runs.
Then i increase length to 30 minutes and heart rate drops from 87% - 90% to 82% - 85% then i build to 40 minutes and that is the point where i speed up.
I tend to find those 20' blocks the easiest. And i do a block of 7 days to introduce pace usually. theother days are runs of 20' easy. I don't do long runs because i don't need to. It is all in the plan. I do do 100's to 200's once a week in the summer and do complementary training like weights, cycling, swimming but most of this is easy. It is all around those 3 - 4 hard days for me.
I do these runs on the tm, and in the summer outside.
I work all zones throughout the phases. Usually a cycle takes 3 - 4 months and then i increase the speed 0.5 km/h. I know it is slow but i keep on improving.
In the winters i usually do those 20' runs to 40' runs, weights, swimming.
