well... I just passed my rather arbitrarily set (I basically went 100km/week sounds good - minus 2 weeks for whatever, this year: corona) goal for this year of half thatto crack 10tkm of cycling in 2021.
Quite alright, I feel, for 99.5% (or thereabouts) of purely excercise riding. Next year I'll do the office trip at least once (60km one way)...
Still: 700 km ahead you say? so higher goal next year yeeeees!
