Estonia takes control at Adventure Racing World Championship in Corsica

The lead changed hands on day 2 at the Adventure Racing World Championship in Corsica, with Estonia Ace/La Sportiva moving ahead of the French favorites. More course time remains, and the first teams are not expected to finish until Oct. 6 at the earliest.

Why it matters: - The world championship is still in its early stages, but the leaderboard has already shifted from French control to an Estonian lead. - The race still has several days to run, so navigation, sleep strategy and mountain conditions could keep reshaping the outcome. - The winners are not expected at the finish in Ile Rousse until Tuesday, Oct. 6 at the earliest.

What happened: - Through the first night and second day of racing in Corsica, teams changed from coastal paddling to mountain trekking across some of the island’s toughest terrain. - Estonia Ace/La Sportiva, ranked world No. 2, moved into the lead by dusk on day 2 while trekking across the Cuscione plateau toward TA5 in Zivaco. - Team Tactical Foodpack of Estonia climbed into second place later in the day. - Teams from Spain, Finland and Canada also moved into the top 10. - Kailas Fuja of Brazil, ranked world No. 3, continued a comeback after an early navigational mistake.

The details: - The race started with teams paddling along the coast from Aleria to Solenzara in darkness. - Sea conditions were ideal overnight, but staying awake became a major challenge. - Adam Rose of Beacon AR said his teammates were singing and asking him questions to keep him awake. - Sunrise revealed views of the granite peaks of the Aiguilles de Bavella before teams headed inland. - At Solenzara, teams portaged kayaks over sand dunes to reach Transition Area 4 and switch from kayaking to trekking. - 400team Altore chose to stop for two hours of sleep at the transition instead of pushing on in the dark. - Teams must take a mandatory 10 hours of sleep at any manned checkpoint or transition area during the race. - Stage E covers 72 km across the Aiguilles de Bavella and Monte Incudine. - The stage includes 4,320 meters of elevation gain and requires off-trail travel through mountain scrub and rocky terrain. - The Fiumicelli Canyon section forced teams to swim, jump, climb and walk downstream between high cliffs and over boulder-strewn ground. - Precise navigation remains a major factor in deciding time gaps on the stage. - By the time teams passed Col de Bavella at checkpoint 5, Estonia Ace/La Sportiva had built a significant lead and Tactical Foodpack had moved into second. - The second night is expected to keep teams high in the mountains as storm clouds, heavy rain and dense mist move in. - Fast teams are projected to take more than 24 hours on Stage E, while the slowest could take more than 40 hours.

Between the lines: - The early race has become a test of more than speed. - Sleep timing, route choice and technical proficiency are shaping the leaderboard as much as raw fitness. - The weather shift could widen gaps for teams that struggle in darkness, rain and limited visibility. - Estonia’s rise suggests the course is rewarding teams that combine strong navigation with efficient pacing in the mountains.

What's next: - Teams will continue through the second night and deeper into Stage E under difficult mountain conditions. - More position changes are likely before the field reaches the finish at Ile Rousse. - Race fans can follow live satellite tracking, photos, videos and reports on the official race website and the AR World Series site. - Updates are also available through the AR World Series social channels.

The bottom line: - Day 2 turned the race from a French-led opener into an Estonian lead, but Corsica’s mountains, weather and sleep rules mean nothing is settled yet.
