Race briefing
140.6 course227 km · 832 m gain · 0% uphill
- Flat
The published GPX measures 227 km with 832 m of climbing, 4 m per km. 46% of the gain sits in the first half.
- 6 laps of 37.8 km: you run the same loop 6 times, so the easy feeling on lap one means little.
- At km 3.7 you pass right by the finish area with 223.3 km still to go; the noise there breaks more races than the climbs do.
- Km 94.3 to 174.6 is the same ground you covered at km 4.3; note your pace on the first pass and use it as the yardstick on the second.
Course-profile notes are generated from GPX grade data; terrain, rules, aid stations and weather are added only when separately sourced.
