80/20

What it is and who it is for

Plans that put about 80% of running time at low intensity, for a range of experience levels.

Most training is easy, with a smaller share at higher effort.

80/20 plans organize training around an intensity split. Coach adjusts the mix as you train, while keeping most running easy.

Separating easy volume from harder work leaves room to recover.

An exact 80/20 split is not a target for every Coach week.
