The race, in three figures
The race, in words
Klaas Sybrand Jissink finished in the top 10% of the field at Heerenveen 2025, in 1:05:19 for 39th of 1,217 men in the Open division.
The burpee broad jumps were where this race was made, 2:19 ahead of the median. Paced to finish: the second half went 2:22 better against the middle of the field than the first. Time in the roxzone, 6:24, was faster than 88% of the field.
Athletes who raced both Heerenveen 2025 and Amsterdam 2024 were 2:40 faster here, so this time looks a little better than it was.
