@bergmeister Thanks! It was about 330 km in 7 days, so like 40-50 km per day (depends on wind and snow).
We mostly moved relatively close to the coast, except one time when we crossed the lake and returned back (about 40 km one way). And we mostly camped on shore except one night in the middle of the lake.
It's lake Baikal, old trip from 2019.
