World's Hardest Flash - Adam Ondra Climbs 5.15 (9a+) First Try
2018 · 11 min · Sport Climbing · Reel Rock
This piece documents Adam Ondra’s flash of Supercrackinette, a 9a+ (5.15a) sport route at St Léger in France. Flashing here means climbing the route clean from bottom to top on the first try without falling; Ondra set himself the goal of being the first person to flash a route at that grade and succeeded on this line in 2018 on a route by Alex Megos. The film shows the approach to the lead, the sequence-reading, and the single successful attempt. The material matters because flashes at the very highest sport grades are rare and teach as much about rehearsal, beta and pacing as they do about raw power. This clip — an excerpt associated with the Age of Ondra / Reel Rock 13 coverage — is useful for seeing how an elite climber converts route inspection and practiced moves into a one-try send on sustained, technical 5.15 climbing.
Review
Eleven minutes on one attempt, and one of the most instructive climbing clips online. On February 10, 2018, Adam Ondra flashed Supercrackinette, a 9a+ at Saint-Léger-du-Ventoux that Alex Megos first climbed in 2016, meaning he climbed it clean, bottom to top, first try. Reel Rock's excerpt shows the approach to the lead, the sequence reading and the single successful go.
This is for climbers who want to see how route inspection and rehearsed moves become a one-try send on sustained 5.15 terrain. The route has no single crux, just 25 to 30 hard moves through an overhang into an awkward 8b+ crack, and the film lets you watch Ondra read all of it from the ground. Skip it if you want more than the attempt. There is no history of the route and little about why the flash mattered beyond the fact that it had no precedent.
What works is the pacing on the lead. You can see where Ondra slows down and where he commits, and the difference is the whole lesson. What it leaves out is Megos. His first ascent gets a mention and the film moves on.
3x 8C Flash in 2 Weeks is Ondra doing the same thing on boulders eight years later, with the ethics argued out loud. This is the route version, quieter and earlier, and the one that established the idea that flashing at this level was possible at all.
