The race, in three figures
The race, in words
In the Open division at Rotterdam 2025, Boudewijn Groosman crossed the line in 1:22:56: 501st of 1,283 men, faster than 61% of the field.
A station race more than a running one: 71% of the field beaten on the stations, against 51% on the runs. The sandbag lunges were where this race was made, 0:39 ahead of the median. A harder second half: 1:04 more lost to the middle of the field after halfway than before it.
Rotterdam ran fast: the 1,452 athletes who also raced elsewhere this season were about 0:39 quicker here than at their other races.
