40K: 40.9 km, 1,808 m of climbing · 20K: 20.9 km, 882 m of climbing. Values are measured from the organiser's published course files.

From easiest to hardest: 20K (km-effort 30, XS) → 40K (km-effort 59, S). Ranked by km-effort (kilometres plus 1 for every 100 m of climbing), measured from the course files.

Over 40.9 km there is 1,808 m of climbing in total, 44 m per kilometre. About 13% of the course is flat. A trail course with distinct climbs. Km-effort is 59, which puts it in the S category on the ITRA scale. This value is calculated from the course file. Official ITRA scores are awarded only by ITRA, and only to races registered and certified with it; this number is not that score. By km-effort it is harder than 76 of the 103 courses whose files we have measured in the calendar; difficulty rank: 26.

The biggest climb is between km 11.3 and km 21.0: 879 m net at an average gradient of 9.1%. Its steepest 250 m section averages 17%. The course has 2 distinct climbs.

Share of the distance: 23% steep climbing (8% and more) · 20% climbing (3–8%) · 12% flat · 20% descending (3–8%) · 25% steep descending (8% and more). Gradient was measured at equal intervals from the elevation in the course file.
