A flat two-loop course
The start is at 9 a.m. on the Quai Maubec and Quai Louis-Durand, split into two starts that merge after 610 m (about 0.4 miles). The certified 26.2-mile course is two loops within the city; on the organizer's published profile it stays below 25 m (82 ft) of altitude. Sixteen bands play along the route, and the end of the first loop, at halfway, gives you a checkpoint.
In late November it is cool by the ocean, with a risk of rain. Do at least one long run in your race kit, in the rain if the chance comes: better to discover chafing in training than at mile 19.
The calendar from September
A late-November race is prepared from August for 16 weeks, or from early September for 12. It is the back-to-school plan par excellence: the peak load falls in October, with ideal temperatures for long runs.
The AI coach sets the plan length from the exact date you give it and from your volume read on Garmin. It starts with a numbers portrait to confirm: sessions per week, kilometres, longest run, VMA and its source.
Pacing strategy and the westerly wind
The route alternates sheltered city sections and an exposed seafront. The instruction: target pace in town, low end of the range into the wind, never forcing to catch up. Over two loops, what you lose on the first pass you get back on the second.
- Km 1 to 3: target pace + 10 s/km.
- Km 4 to 35: target pace, low end of the range into the wind.
- Km 36 to 42: by feel, the port crowd carries you.
The watch carries the pace range per segment. Schedule the plan's "Race" session: it alerts you if you go out too fast in the excitement of the Old Port.
