The race, in three figures
The race, in words
In the Open division at Chiba 2026, 祐紀 有泉 crossed the line in 1:31:36: 145th of 299 men, faster than 52% of the field.
The runs carried this race: faster than 57% of the field over the eight kilometres, against 37% on the stations. The wall balls cost the most time: 2:06 slower than the median. A harder second half: 3:22 more lost to the middle of the field after halfway than before it.
Athletes who raced both Chiba 2026 and Osaka 2026 were 2:03 faster here, so this time looks a little better than it was.
