This small climb is tricky as it involves several small turns and one needs to calculate them so pedals don't hit the side roots and the log.
Successful for me gear combination: GRANNY and SECOND BIGGEST ring in the back. Did it is sitting position.
I used to do it with the MIDDLE ring and the BIGGEST ring in the back but it is less smooth and most likely I will need to stand. Too much available torque (the use of the MIDDLE ring up front) I find on such stretch is not necessarily good.
