An urban course, from the Capitole to the Stadium
Start on Boulevard d'Arcole, finish on Boulevard Lazare-Carnot: in 2026, the Marathon des Géants passed the Place du Capitole, the Canal du Midi, the Piste des Géants, the Cité de l'Espace, the Oncopole, ENAC and the Île du Ramier, and ran through the Stadium de Toulouse. The organizers announced 217 m (712 ft) of total elevation gain.
217 m (712 ft) over 26.2 miles: a runnable course, but not a flat one, and your target paces should account for it. The 2027 route has not been published yet and may change depending on permits: check the final version and the GPX file on the official site as soon as they are out.
Preparing an early-November race in the South-West
For an early-November race, the 12-week plan starts on a Monday in mid-August, or from mid-July in its longest, 16-week version. Toulouse summers are hot: the AI coach applies its rule for days above 28 °C (82 °F), paces reduced by 3 to 5% and heart rate as the main target.
Run quality sessions early in the morning and keep long runs before 9 a.m. The weekly review, with the training load read from Garmin, confirms progress even when summer times look disappointing.
Pacing strategy for Toulouse
A crowded start in the centre and 217 m (712 ft) of climbing spread over the distance: the course punishes a fast start. The instruction: first 2 miles at target pace plus 15 seconds per mile, then steady target pace, accepting a few lost seconds on the climbs without trying to win them back on the descents.
- July-August: volume, heat-adapted paces.
- September to early October: long runs up to 2 h 45, marathon-pace blocks.
- October: taper, last long run three weeks out.
The finish comes back into the centre with the crowd. Wait for the last kilometre to let it go.
