Thank you for your encouragement and advice Dave and Ras!
The Sudovian Mountains (as some call the area on the borderline of Poland and Lithuania in the Suwalki Gap) is the land of the most premium gravel roads in whole Poland. There are almost no flats only violent ascents and descents there. Here is the elevation profile for the Sprint Race:

It is (intentionally) a 50-miler.
Do I believe in the 26% ascent? Not. Do I believe in the 16% climb? Yes. I even do not intend to pedal on the descents because I need to conserve the battery, so let the gravity do its job. I am even more afraid of the descents as these are steep, short, and often end with a sharp turn! All of this makes the race so exciting!
I cannot borrow the Trance E+ from Jacek now (he is travelling to Bieszczady Mountains -- the opposite side of Poland -- on the same weekend; his younger son will be my transport though).
