The race, in words
Laura Derks finished 199th of 203 women in the Open division at Rotterdam 2025, in 2:20:39.
The sandbag lunges cost the most time: 3:23 slower than the median. A harder second half: 9:28 more lost to the middle of the field after halfway than before it. 10:14 in the roxzone was slower than 85% of the field.
Rotterdam gave the field time back: about 0:50 faster than the average race this season, by 605 athletes who raced both. That was 10:23 off the time at Chicago Navy Pier 2024.
