Race preparation guide
Trail de Millau 2026: complete FR + EN guide
100 km de Millau - Ultra 100 km needs precise planning: 100 km, 1100 m of climbing and logistics centred on Millau, Parc de la Victoire and the Grands Causses. This guide uses the 100 km de Millau as the Millau reference format: a historic rolling road ultra that leaves town toward the Tarn valley, the causses and Saint-Affrique before returning to Parc de la Victoire. It is not an alpine trail, but the duration, rolling climbing and support logistics make it a full ultra preparation project.
Race overview
Trail de Millau is part of the Week 25 TrailCompanion guide batch. This page condenses the practical decisions to make before booking: reference format, terrain, access, lodging, gear and official links to check before travel.
The key is not distance alone. On this kind of trail, success depends on pacing the climbing, managing aid stations, adapting to local weather and arriving rested with a simple bib, start and post-race plan.

Create my Prep for this race →What you actually need to prepare
Build preparation around hilly long runs, controlled descents and hike-run blocks. For 100 km, you need to hike early without losing rhythm, run the easier sections and eat before intensity shuts down appetite.
TrailCompanion Prep then turns the guide into a checklist: tested kit, lodging, transport, documents and week-by-week nutrition reminders.
Trail de Millau mandatory / recommended gear
The official organiser list always comes first. This baseline covers the realistic needs to prepare your pack before bib control.
- Very stable road or door-to-trail shoes already tested on long asphalt runs and rolling descents.
- Light belt or vest with water, food, salt, charged phone and an emergency layer for waiting or night sections.
- Lighting and reflective items if your pace takes you into the evening or toward the 18-hour limit.
- Clear support plan: bike, bags, meeting points, dry clothes and written instructions if timing slips.
- Sun protection, cap, anti-chafe cream and a foot-care plan, because most wear comes from repeated road impact.
Recheck the official rules during race week: weather, timing and gear requirements can change.

Logistics to solve early
Start logistics from Millau, Parc de la Victoire and the Grands Causses. Confirm bib pickup, parking or shuttles first, then choose lodging. An early start or late return can completely change the best base.
Keep the official links in your Prep: race website, registration page, rules, access map and last-minute instructions. This guide gives the framework, but the organiser remains the final source.
Transport to Millau, Parc de la Victoire and the Grands Causses
Millau can be reached by train via Béziers, Montpellier, Clermont-Ferrand or Rodez depending on connections; check timetables early because regional services can be sparse on race weekend.
By car, plan to arrive the day before: bib pickup, parking around Parc de la Victoire, bike support and valley traffic require more margin than a simple city race.
Where to stay for Trail de Millau
Staying in Millau is the simplest choice for the 8:00 start, late finish and no-transfer recovery after 100 km.
Creissels, Aguessac, Saint-Georges-de-Luzençon or lodging in the gorges can work with a car, but only if your support person manages transfers and the night return.
