  • La LEC XPO vuelve este año a la final de verano de la LEC en Niza (Francia) y, sí, ¡es gratis!
  • El Jardin Albert 1er se transformará en una experiencia inmersiva de League of Legends los días 19 y 20 de septiembre.
  • Este año se celebrará una fiesta de visionado de la LEC al aire libre del 19 al 20 de septiembre en el Théâtre de Verdure de Niza.

 

Estamos deseando poner rumbo a Niza (Francia) para la final de verano de la LEC 2026. Pero además del torneo de tres días en el estadio, teníamos guardado un secreto más…

Además de unas partidas alucinantes, queremos ofrecer a nuestra comunidad la experiencia cultural de LoL que se merece y por eso trajimos la LEC XPO de vuelta. Este año convertiremos el Jardin Albert 1er, en pleno centro de Niza, en un fin de semana dedicado por completo a League of Legends y con entrada gratuita para todo el mundo. Con los años, la final de verano de la LEC se ha convertido en mucho más que la mejor competición de EMEA: es una cita anual única que reúne a la comunidad para celebrar el vibrante mundo de Runaterra más allá del estadio.

Por primera vez, llevamos la emoción del estadio hasta la XPO con una fiesta de visionado al aire libre. Los fans podrán reunirse para vivir cada partida, cada jugada y cada momento del fin de semana de la final de la LEC aunque no estén dentro del Palais Nikaïa.

Estamos deseando daros la bienvenida a Niza y celebrar juntos el mejor fin de semana de la temporada de la LEC.

LEC XPO 2026

Tras el éxito de la LEC XPO en los últimos años, estamos encantados de traerla de vuelta, esta vez en Niza. La XPO reúne a los fans de League of Legends y de LoL Esports en un evento que va más allá de la competición y celebra su afición y la cultura que han construido.

La XPO se celebrará en el Jardin Albert 1er el sábado y domingo del fin de semana de la final de verano, los días 19 y 20 de septiembre. Tanto si sois fans de toda la vida, si queréis enseñarle el juego a alguien nuevo, como si solo buscáis un sitio donde celebrarlo con la comunidad, en la LEC XPO habrá algo para todos.

Las puertas de la XPO abrirán a partir de las 11:00 (horario peninsular) los dos días, con entrada para todos los públicos y totalmente gratuita. El sábado, la XPO cerrará a las 19:00 y el domingo, a las 18:00.

Quienes nos acompañen podrán disfrutar de un montón de actividades de League of Legends gracias a nuestros colaboradores y equipos. Podréis recorrer los stands de colaboradores como KIA, Kit Kat, Euronics, Red Bull y ExpressVPN, entre otros. Además, los fans tendrán la oportunidad de conocer a algunos de los grandes nombres de los esports: G2 Esports y Karmine Corp asistirán, junto con otros equipos que anunciaremos más adelante.

Acompañadnos en una celebración cultural por toda la ciudad que dará vida a lo mejor de Runaterra durante dos días inolvidables. Descubrid experiencias de otros títulos de Riot Games, como Teamfight Tactics, y haceos con productos oficiales de Riot Games.

Os contaremos más detalles a medida que se acerque el evento, pero ya os podemos adelantar que será una gran ocasión para reuniros con amigos y celebrar el juego que todos adoramos.

Fiesta de visionado de la final de verano de la LEC

¿No podéis entrar al estadio? ¡No pasa nada! Como novedad de este año, podréis vivir la acción en nuestra fiesta de visionado diaria, el sábado y el domingo, en el recinto de la XPO. Reuníos con otros fans de la LEC en el Théâtre de Verdure del Jardin Albert 1er para disfrutar de una experiencia de esports al aire libre. Disfrutad de las partidazas bajo el sol, al lado del mar, y empapaos de un ambiente eléctrico.

Tanto la fiesta de visionado como la XPO son totalmente gratuitas, pero os animamos a conseguir una entrada para la fiesta de visionado para aseguraros de que podéis acceder. Preparad un pícnic, reuníos con vuestros amigos bajo el sol mediterráneo y ved juntos las partidas de la LEC.

No os perdáis nada: seguid a la LEC en redes sociales y estad atentos a LoLEsports.com para conocer todas las novedades.

Acerca de League of Legends

League of Legends, publicado en 2009, es el título con el que debutó Riot Games y uno de los videojuegos competitivos más jugados del mundo, ya que cuenta con millones de jugadores diarios y está disponible en más de 20 idiomas. En LoL, un pilar de los MOBA, dos equipos de cinco poderosos campeones se enfrentan para destruir la base enemiga en un juego que fusiona la velocidad, profundidad táctica e intensidad de la estrategia en tiempo real con los elementos de inmersión de un RPG.
La experiencia de juego y las historias de LoL siguen evolucionando año tras año, y Riot crea originales experiencias como K/DA, historias detalladas como las de Guardianas de las estrellas y Florecer espiritual, y ajustes de equilibrio con los que asegurar la integridad competitiva. Al ser la piedra angular del universo de Runaterra, los campeones de LoL han aparecido en canciones, cómics, juegos basados en los títulos originales, figuras coleccionables, juegos de mesa, series de televisión y mucho más. El Campeonato Mundial de League of Legends anual es uno de los torneos de esports más vistos y uno de los eventos deportivos más importantes y populares del mundo.
