However, even with these iconic climbs, the 2025 route has
yet to surpass the stage with the highest elevation gain in
Tour de France
history. That record belongs to Stage 18 of the 1983 Tour, which ran from
L'Alpe d'Huez to Morzine, covering an astounding 6,400 metres of elevation
gain, according to
La Flamme Rouge. Riders that day faced an endless array of punishing climbs,
making it a battle of resilience and sheer grit. Jacques Michaud emerged
victorious in just under eight hours, a testament to the extreme difficulty of
the course. Meanwhile, Laurent Fignon ultimately triumphed in the overall race,
claiming his first Tour de France title in a year marked by intense competition
and formidable terrain. It was also the year that Sean Kelly of Ireland claimed
the points classification.
While the 2025 edition brings its own challenges, including
the much-anticipated returns of Mont Ventoux and Col de la Loze, the 1983 stage
remains a legendary benchmark. But for now, Stage 18 of 1983 holds its place as
one of the most daunting days in Tour history, a reminder of the brutal demands
that define cycling’s most iconic race.
