As with any outdoor sport, the decathlon is also influenced by the weather. Bad weather, especially rain, is not only uncomfortable for both athletes and spectators, but can also affect performances and results. You probably still remember the massive rainstorm during the World Championships in Helsinki 2005. Although the stadium was literally under water, the decathletes had to continue with the high jump. Despite those conditions, Attila Zsivoczky managed to clear 2.15 m, which was a truly outstanding performance.
One of the most remarkable examples came in Helsinki 1994, when Alain Blondel won with a 5.40 m vault despite the pouring rain and practically landed in a pool of water.
Let’s remember some unforgettable moments from the 1994 European Championships in Helsinki.
But it's also a little disadvantage for the athletes if it's too hot, as this can easily weaken the body and impair the results. Probably the best weather for a decathlon competition is a sunny day, not too hot, probably around 25°C. And, of course, a slight tailwind could also be an advantage, especially in running and jumping events, while for discus and javelin throw the athletes might prefer wind from the opposite direction.
