The 2026 course
Start on Boulevard d’Arcole. The course passes through Compans-Caffarelli (km 1), near Place Saint-Pierre and by the Capitole (km 3), then heads down via Place du Parlement (km 4) and Saint-Michel (km 5). It reaches the Île du Ramier over the Anita-Conti footbridge (km 6), runs out to the Oncopole (km 8 to 12), then comes back up the left bank of the Garonne along the Allée des Moulins to Saint-Cyprien (km 15). Back to the right bank over the Pierre-de-Coubertin bridge (km 17), then east: Avenue Crampel (km 19), Montaudran and the Piste des Géants, near the ENAC (about km 21 to 28), the Cité de l’Espace (km 30), the Hers greenway (km 31 and 32) and Les Argoulets (km 34 and 35). Back towards the centre through Bonnefoy (km 37), the Canal du Midi at Port Saint-Sauveur (km 39) and the Grand-Rond (km 41), finishing on Boulevard Lazare-Carnot.
What the race asks of your training
A build-up through the summer
To race on 1 November, a 16-week build-up starts in early July, and the long runs fall in the heat of a Toulouse summer. Doing them early in the morning avoids cutting them short, and judging your marathon pace on times skewed by the heat.
Fast, with a drag near the end
217 m of climbing over 42 km: no real hill, but bridges over the Garonne and, according to the published track, a drag of about 20 m between Les Argoulets (km 34) and the city centre (km 38). Finishing a few long runs with 15 to 20 minutes at marathon pace prepares you for it.
A wake-up before dawn
Pens start between 8 and 8:30 am, but the organisers advise reaching the bag drop from 6:45 am, while it is still dark. Doing one or two long runs at the same time of day lets you settle your wake-up time, breakfast and warm-up.
Running with your own flask
No plastic bottles: tap water is served in reusable cups, and the organisers advise bringing a flask, bottle or hydration vest to fill at the aid stations. Testing this kit on your long runs means race day is not the first time.

Why this plan works
Science-based periodisation
Base → build → specific → taper, with a recovery week every 3 to 4 weeks. Load goes up, but never two hard weeks in a row without a breather.
Paces, not vague feelings
Every session has target zones (pace, HR) computed from your MAS or a reference performance. A MAS test is built into the plan if you don't know yours.
A plan that listens
After each session you rate how it felt (RPE). Too hard? The plan eases what follows. Skipped a session? It reschedules or absorbs it.
On your watch
On Garmin with the Endu app, on COROS by direct sync: the guided workout shows up on your wrist, step by step.

- Can I still enter the 2026 Toulouse Marathon?
- The website says entries are possible until 30 October 2026, within the limit of 7,500 places. The half marathon is sold out.
- Marathon de Toulouse: how many weeks of preparation?
- For an athlete at intermediate level, Endu builds a 17-week preparation. If your race is closer, the plan compresses phases while keeping the taper; if it's further away, it lengthens the preparation, and when the gap is large the preparation starts right away, gently and at your current volume, before building up.
- Is this plan well built?
- Pass at Endu’s plan check, the same as for any plan: 16 of 16 checks passed. A 17-week build (recommended minimum: 12); a longest run never more than 8% above the previous month’s; volume rising at most 7% from one week to the next; 89% of the time at easy effort; the longest session 3 weeks before the race; a taper cutting volume by 61% in race week. The rules and their sources are public on endu.fr/en/controle-technique.
- How many sessions per week?
- This example has 4 sessions per week. You choose 3 to 7 training days and the exact days (e.g. Tue, Thu, Sat, Sun): the plan sticks to them.
- I'm a beginner, is this plan for me?
- The plan adapts to your declared level (beginner to semi-pro): starting volume, progression and intensity change. Endu also offers a "Discovery" mode without a race to build a base first.
- Can I follow sessions on my watch?
- Yes, on Garmin and COROS. On Garmin, the Endu app (Connect IQ Store) shows today’s session and starts it as a guided workout. On COROS, link your account from your profile: your running, trail and cycling sessions land in the watch calendar. Other brands are not supported yet.
- How much does it cost?
- 14-day free trial, then €7.99/month with no commitment or €59.88/year (€4.99/month). Unlimited objectives and sports.
