World's Hardest Flash - Adam Ondra Climbs 5.15 (9a+) First Try

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.
