The hunt for Running Stones has reached boiling point on the French Riviera, transforming the Nice Côte d'Azur by UTMB into a high-stakes eliminator for the world's elite. As the World Series calendar winds down, this French fixture has become the ultimate lifeline for those seeking to secure their spot in the Chamonix 2027 grand final without facing the lottery, pushing the start list's depth to levels rarely seen at this stage of the season.
The Mercantour hell and the dream of the Promenade des Anglais
The media spotlight is firmly on the Ultra Trail Métropole Nice Côte d'Azur - 100M. This isn't just a 165-kilometer trek; it's a masterclass in technical survival starting in Auron and devouring 8,900 meters of elevation gain. Runners will face pure alpine terrain, with passes exceeding 2,000 meters where the air gets thin, before launching into a vertiginous descent toward the Mediterranean. Circuit veterans warn: the first 100 kilometers through the Mercantour National Park are a constant leg-breaker that often leads to a severe bonk when the coastal heat begins to bite in the final stretch.
Strategic duels in the short distances
While the ultra-runners manage their suffering, the Roubion - Nice - 100K features a much more explosive field. Here, pace management over the 5,400 meters of vertical gain will be crucial to avoid hitting the wall on the technical single tracks winding toward Eze. In the 50K distances, starting from both Levens and the iconic Eze, a frantic battle of rhythms is expected—almost like a road marathon in the final flat kilometers, where transition specialists will make the difference. Organizers have reinforced the aid stations in anticipation of high relative humidity, a factor that could compromise hydration and trigger premature cramping on the final climb before the sea comes into view.
The event's logistics are deployed this year with surgical precision, connecting snowy peaks with the palm trees of Nice. For many, crossing the finish line on September 27th will be more than a sporting achievement; it will be the confirmation that their name will be on the Mont-Blanc start line next August.
