57K: 57.6 km, 1,105 m of climbing · 21K: 20.4 km, 408 m of climbing · 14K: 14.4 km, 365 m of climbing · 8K: 5.2 km, 76 m of climbing. Values are measured from the organiser's published course files.

From easiest to hardest: 8K (km-effort 6, XXS) → 14K (km-effort 18, XXS) → 21K (km-effort 24, XXS) → 57K (km-effort 69, S). Ranked by km-effort (kilometres plus 1 for every 100 m of climbing), measured from the course files.

Over 57.6 km there is 1,105 m of climbing in total, 19 m per kilometre. About 45% of the course is flat. A rolling course: ups and downs, but not a mountain course. Km-effort is 69, 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 94 of the 119 courses whose files we have measured in the calendar; difficulty rank: 25.

The biggest climb starts right after the start and runs to km 12.2: 402 m net at an average gradient of 3.3%. Its steepest 250 m section averages 16%. The course has 2 distinct climbs.

Share of the distance: 4% steep climbing (8% and more) · 21% climbing (3–8%) · 48% flat · 26% descending (3–8%) · 1% steep descending (8% and more). Gradient was measured at equal intervals from the elevation in the course file.

There is 1,091 m of descent in total. The longest uninterrupted descent is between km 50.2 and km 56.2: 236 m. The steepest descent is around km 20.6, with an average gradient of 9%.

The course splits into 12 sections: 0.0–4.6 km gentle climb (+108 m); 4.6–7.4 km climb (+177 m); 7.4–15.2 km gentle climb (+114 m); 15.2–18.8 km flat (+39 / −17 m); 18.8–22.4 km descent (−196 m); 22.4–25.4 km gentle climb (+87 m); 25.4–30.2 km descent (−170 m); 30.2–32.4 km climb (+123 m); 32.4–35.8 km gentle climb (+86 m); 35.8–41.8 km gentle descent (−99 m); 41.8–50.4 km rolling (+136 / −171 m); 50.4–57.6 km gentle descent (−203 m).
