17-18 km one way. So tried last year and was kinda perfect. Took like 30 mins and if I feel like it I can expand it on my way home quite easy :)
That's quite fast! For me it's a 16,5 KM one way ride to the office. It takes me just over half an hour.
We will have to wait and see if I have the same speed now as then, was in way better cycling form then 😅
