The race, in three figures
The race, in words
Stefan Grootkarzijn finished in the top 10% of the field at Maastricht 2025, in 1:06:50 for 38th of 1,352 men in the Open division.
The burpee broad jumps were where this race was made, 2:17 ahead of the median. Paced to finish: the second half went 1:46 better against the middle of the field than the first. Quick through the roxzone: 5:09, ahead of 97% of the field.
Athletes who raced both Maastricht 2025 and Heerenveen 2025 were 1:42 slower here, so the course was tougher than the clock suggests.
