From easiest to hardest: 5K (km-effort 6, XXS) → 10K (km-effort 11, XXS) → 21K (km-effort 24, XXS) → 22K (km-effort 26, XS) → 42K (km-effort 47, S). Ranked by km-effort (kilometres plus 1 for every 100 m of climbing), measured from the course files.

Over 42.2 km there is 430 m of climbing in total, 10 m per kilometre. About 75% of the course is flat. A rolling course: ups and downs, but not a mountain course.

Official ITRA scores are awarded only by ITRA, and only to races registered and certified with it; this number is not that score. The value is close to a category boundary: with the organiser’s stated distance and climbing it may fall into the XS category. By km-effort it is harder than 81 of the 117 courses whose files we have measured in the calendar; difficulty rank: 35.

Share of the distance: 5% climbing (3–8%) · 88% flat · 6% descending (3–8%). Gradient was measured at equal intervals from the elevation in the course file.
