The race, in words
1:55:39 at Chiba 2026 put 由布幸 石川 475th of 589 women in the Open division.
The runs carried this race: faster than 47% of the field over the eight kilometres, against 10% on the stations. If there was time left out there, it was on the sled pull, 5:23 behind the median. Stronger after halfway: 5:03 better against the middle of the field than before it.
Athletes who raced both Chiba 2026 and Osaka 2026 were 2:38 faster here, so this time looks a little better than it was.
