The 2026 Tour de France is shaping up to be one of the toughest network performance tests for mobile operators in Europe, with the 3,333-kilometer race stretching from Barcelona to Paris across urban centers, mountain passes, and remote rural regions. Analysis based on Speedtest Intelligence data from 2025 reveals significant differences in operator performance and highlights areas where additional network investment and temporary infrastructure will be crucial.
The study used the Speedtest Connectivity Score, a composite metric measured on a 0-100 scale, combining Speed Score (50 percent), Video Streaming Score (25 percent), and Web Browsing Score (25 percent), to evaluate overall user experience along the 21-stage route.
Orange Emerges as the Most Consistent Operator
Among French mobile operators, Orange delivered the most reliable performance throughout the Tour route. Orange’s extensive network footprint and 40 MHz of paired low-band spectrum across the 700 MHz and 800 MHz bands enabled stronger rural and mountain coverage than rivals.
Orange achieved Speedtest Connectivity Scores above 80 at most French stage locations, including Bordeaux (87), Dole (87), Mulhouse (88), Pau (85), and Paris (86). Even in challenging locations such as Évian-les-Bains (69) and Bourg-d’Oisans (67), Orange maintained relatively stable performance.
Importantly, Orange’s score dropped below 70 at only four of the 33 French stage locations analyzed, making it the strongest operator for route-wide consistency.
Barcelona Delivers Strongest Connectivity
The Grand Départ in Barcelona provides the strongest connectivity baseline of the entire race. Stage 1 recorded a route quality score of 96, benefiting from dense urban coverage and competition among five Spanish operators.
In Barcelona, Movistar led with a Speedtest Connectivity Score of 83, followed closely by Orange at 82 and DIGI at 81. DIGI also topped performance in Tarragona with a score of 85, highlighting the success of its aggressive 5G expansion strategy.
However, connectivity declines sharply after the race crosses into France. Route quality falls into the low 70s by Stage 4 and continues deteriorating through central France.
Rural France Creates Biggest Challenge for Operators
Contrary to expectations, the weakest mobile network performance is not found in the Alps or Pyrenees but in rural central and southwestern France.
Stage 8 from Périgueux to Bergerac recorded a route quality score of 61, while Stage 9 from Malemort to Ussel delivered the lowest score of the entire Tour at 59.
At Bergerac, Orange maintained a score of 84, while SFR dropped to 60 and Bouygues Telecom to 62. At Ussel, all four operators clustered between 78 and 82, indicating limitations in the underlying network infrastructure across the region.
The corridor spanning Stages 8 through 14 consistently recorded route quality scores between 59 and 68, making it the most vulnerable section of the Tour for operators managing spectator demand and media traffic.
Free Mobile and Bouygues Telecom Show Coverage Gaps
The data highlights significant performance volatility for both Free Mobile and Bouygues Telecom.
Free Mobile recorded the lowest individual operator score on the entire route, posting just 50 at Les Angles and 58 at Orcières-Merlette. The operator’s lack of 800 MHz spectrum continues to create challenges in rural and mountainous areas despite investments in 700 MHz and 3.5 GHz frequencies.
Bouygues Telecom also experienced major performance drops in difficult terrain, scoring 52 at Gavarnie-Gèdre and 53 at Thoiry. While the operator achieved strong results in cities such as Bordeaux (87), Pau (85), and Orcières-Merlette (89), coverage weakened considerably in remote locations.
SFR Delivers Balanced Performance
SFR occupied a middle ground between Orange and its competitors. With 30 MHz of paired low-band spectrum and 80 MHz of 3.5 GHz holdings, SFR maintained relatively stable performance throughout the route.
The operator led at Les Angles with a score of 82 and generally outperformed Free Mobile and Bouygues Telecom in rural areas. However, SFR struggled in the Dordogne region, falling to 60 at Bergerac, one of its weakest performances on the Tour route.
Massive Temporary Infrastructure Required
The Tour de France presents unique engineering challenges for operators. Unlike a stadium event, connectivity requirements move daily across routes ranging from the 19.7-kilometer opening time trial to the 205-kilometer Dole-to-Belfort stage.
Historically, Orange deployed approximately 40 temporary mobile relay sites during the race and upgraded stage backhaul capacity to 10 Gbps in 2023, a fivefold increase compared with 2022. Around 13 of those temporary sites remained operational after the race.
During previous editions, Orange handled more than 100,000 calls and connections in less than an hour at Mont Ventoux in 2021 and recorded 32 million connections during the Briançon–Alpe d’Huez stage in 2022.
The race also relies on around a thousand temporary frequencies coordinated by France’s national spectrum agency, ANFR, to support broadcasting, race communications, and operational services.
Key Areas Requiring Operator Attention
The analysis identifies three priority zones for network enhancement:
Dordogne-Corrèze corridor (Stages 8 and 9), where route quality scores fall to 61 and 59.
Mountain finishes including Gavarnie-Gèdre, Plateau de Solaison, and Orcières-Merlette, where operator performance varies significantly.
The 26-kilometer Évian-les-Bains to Thonon-les-Bains time trial, which recorded a route quality score of 61 despite its proximity to Geneva.
With an estimated 10 million to 12 million spectators expected along the route, operators will need extensive temporary infrastructure, additional backhaul capacity, and careful spectrum management to maintain service quality during one of the world’s most demanding sporting events. Orange enters the race with the strongest baseline network, while competitors face greater pressure to strengthen coverage in France’s most challenging regions.
