A moment later he arrived and supported his park mate Marwin Talsma who was knocked out on the inside.
van der Poel also broke Sven Kramer's championship record of 12.55.98 in his own shot put.
van der Poel was averaging around 30.3 the first laps, where Abbas' "Mamma Mia" was played in the speakers, and was over 31 on any lap towards the end to turn back and finish for 30 seconds.
The last lap was 29.52.
Canadian Graeme Fish holds the world record of 12.33.86 from 2017.
With 12.42.80, van der Poel is fifth through the ages.
On Saturday, Nils van der Poel also set a Swedish record when he finished second in the 5000 meters with a time of 6.13.03, only beaten by Dutch star Patrick Roest.
At the all-round European Championships, however, no medals are awarded at individual distances.
