Slalom Sudoku (Daily Sudoku League #39)

The meaning of slalom is to zigzag between obstacles. Slalom is one of my favorite puzzle types. Here is the Slalom Sudoku type which appeared recently in one of the WPF Grand Prix 2014 Sudoku championships.

This Slalom Sudoku is my 39th contribution to The League of Extraordinary Ladies and Gentlemen.

Rules of Slalom Sudoku

Classic Sudoku Rules apply. Additionally, some of the rows contain poles. In these rows, the cells between two poles must contain a set of consecutive digits.
