Finding accommodation for the UTMB® can quickly become tricky if you leave it too late. The event attracts runners from over 100 different countries, turning Chamonix into a bustling international hub: demand for lodging surges, and availability shrinks year after year. Here are our guidelines to plan your booking effectively.
More than 6 months in advance
If your entry is confirmed, this is the ideal time to book: you benefit from the widest choice of accommodation and often the best rates, especially if you are looking to stay near the centre of Chamonix. In practice, this means booking as soon as the lottery results are confirmed in February.
Between 3 and 6 months in advance
Good options are still available during this period, but they start to become scarce, especially for specific accommodation types such as chalets or large group apartments.
Less than 3 months in advance
At this stage, finding accommodation in central Chamonix becomes harder. You will likely need to broaden your search to surrounding villages: discover our tips in our guide on Where to stay in Chamonix.
Key points to consider when booking
Consider the total length of your stay: arriving several days before the race to recover from travel, collect your bib, and scout the surroundings can affect accommodation availability across the entire period.
Also remember the night after the finish, which is often overlooked. A runner starting on Friday evening may finish on Sunday: make sure your booking covers the night following your arrival, regardless of what time you cross the finish line.
Finally, location matters: saving money by staying outside Chamonix can complicate access to the race, support zones, and the event atmosphere. Keep an eye out for special offers occasionally provided by certain accommodation providers for UTMB® participants.
Frequently asked questions
Do you really need to book 6 months in advance?
It is not mandatory, but it is the best way to secure the widest choice and the best rates, particularly near the centre of Chamonix.
What should I do if I haven't booked in time?
Broaden your search to surrounding villages such as Sallanches, Combloux or Passy: availability is often better and rates more affordable, all within a reasonable distance of Chamonix.
How many nights should you plan for?
Plan at least from two days before the start until the day after your estimated finish. For the flagship race, this generally means four to five nights, including bib collection and recovery.
