WU20R - world U20 record
CR - championship record
U20NR - national U20 record
PB - personal best

Didn’t finish:
Nikolaos Avgoustos Alexopoulos (GRE), Denis Hrabar (POR), Flor Lambrechts (BEL).
Historical note: Hubert Trościanka’s 400m on 7 August 2025 was remarkable even beyond the decathlon. His 46.21 broke the world U20 decathlon best and would have been fast enough for silver in the individual 400m final at the same championships. A day later, he completed his record-breaking decathlon with 8514 points, improving Niklas Kaul’s eight-year-old world U20 record by 79 points.
