100K: A REDESIGNED ROUTE FOR 2025
With just four months to go until the 4th edition of Nice Côte d’Azur by UTMB® (25–28 September 2025), organisers have unveiled a major update to the 100K route.
The first 40km between Roubion and Brec d’Utelle has been completely reworked. This wilder and more technical new section will take runners through the villages of Ilonse, Bairols, Tournefort and La Tour, offering a more immersive experience in unspoilt natural surroundings. The overall total elevation gain has increased to 5,152m D+ (+ 600m), and the time limit has been extended to 30 hours.
2025 REGISTRATION: FINAL SPOTS REMAINING FOR THE 100M
The 20K, 50K and 100K races are now fully booked. Only a limited number of places remain for the flagship 100M format, which sets off from Auron at 13:00 on Friday 26 September. This 159km challenge, featuring 8,200m of elevation gain, takes runners deep into the Southern Alps and finishes in spectacular style on Nice’s fabled Promenade des Anglais.
CHARITY BIBS: SUPPORTING TWO LOCAL ASSOCIATIONS IN 2025
Nice Côte d’Azur by UTMB® continues to strengthen its commitment to social responsibility in 2025 through its Charity Bib programme – a meaningful way for runners to support local causes while taking part in the event. This year two local associations will benefit from the initiative:
Mission Trekkeurs – dedicated to rebuilding areas impacted by natural disasters
Solidarité 06 – providing support to homeless women in the Alpes-Maritimes region
To date six of the 32 available Charity Bibs have been claimed.
In 2024 the initiative raised €10,495 for Mission Trekkeurs, through bib sales and runner donations.
WOMEN IN TRAIL
Building on the success of the Women in Trail initiative at other UTMB World Series events in France – including Grand Raid Ventoux by UTMB and Trail Alsace Grand Est by UTMB – the 2025 edition of Nice Côte d’Azur by UTMB renews its commitment to promoting equity and supporting female participants.
With women representing 26.6% of finishers in 2024, the event continues to drive progress through a series of concrete actions:
A webinar in September focusing on women in sport
A dedicated WhatsApp group
Free menstrual products and personal hygiene items available at all Aid Stations
Separate, gender-specific facilities, including WCs and changing rooms, to ensure comfort and respect for all
A female point of contact present on-site throughout the event
In addition, UTMB Group has rolled out a flexible and inclusive pregnancy policy across all UTMB World Series events. The policy is designed to support pregnant athletes, partners of pregnant individuals, and those undergoing adoption or surrogacy.
ENHANCED ENVIRONMENTAL COMMITMENT
Since its inception Nice Côte d’Azur by UTMB has placed sustainability at the heart of its operations, implementing concrete measures to minimise its environmental footprint. In 2025 several of these key initiatives will be continued – and in some cases expanded – in close partnership with local authorities and environmental organisations.
Key actions include:
Zero single-use plastic at Aid Stations
No cups or cutlery provided – a Bring Your Own Utensils (BYOU) policy is in effect
Post-race trail clean-up operations after each event
Collaboration with Mercantour National Park to ensure all routes respect sensitive ecosystems
A low-impact transport plan: 88% of runners and over 100 supporters will be transported via 65 shuttle buses – representing an €82,000 investment (+2% compared to 2024)
