After the first day of competition at the IAAF World Championships Beijing 2015, we’ve got the significant numbers of the day:
Number of gold medals won by Eritrea in World Championships history, now the relatively unknown marathon runner Ghirmay Ghebreselassie took the first gold of the championships in a heat-slowed 2:12:28.
Number of previous marathon champions younger than Ghebreselassie.
The finishing position of defending marathon champion Stephen Kiprotich of Uganda.
The position of Mark Korir, the only one of the Kenyan team to finish.
The worst position Jessica Ennis-Hill ever held in the heptathlon throughout the first day. Ennis-Hill had the second-fastest 100m hurdles time, took the lead from Nadine Visser after the high jump, and hasn’t been overtaken yet.
Points separating Ennis-Hill from her British team-mate, second-placed Katarina Johnson-Thompson.
Points separating Johnson-Thompson from fourth-placed Brianne Theisen-Eaton of Canada.
Points separating Theisen-Eaton and third-place Nadine Visser of the Netherlands.
Events left on Sunday to sort out those gaps.
Attempts needed for Christina Schwanitz of Germany to put the shot 20.37m and surpass China’s Gong Lijiao’s 20.30m first-round effort.
Number of marks by all other competitors in the women’s shot better than any mark recorded for Gong or Schwanitz.
World Championship gold medals held by Mo Farah after tonight’s 10,000m final.
Number of men with two consecutive 10,000m titles: Haile Gebrselassie, Kenenisa Bekele, and Farah.
Metres of the 10,000m race which Farah led before his 27:01.13 finish.
The hundredths of seconds by which Farah broke Kenenisa Bekele’s stadium record, set at the 2008 Olympics
Number of 800m semi-final qualifiers with PBs faster than IAAF President-Elect Sebastian Coe. (That would be world record-holder David Rudisha of Kenya.)
Heats, of five, of the men’s 400m hurdles won by Kenyans (Nicholas Bett and Boniface Tumuti).
Number of jumps it took Renaud Lavillenie of France to clear the 5.70m automatic qualifying height in the pole vault, after passing all heights up to that one.
Number of jumps it took defending pole vault champion Raphael Holzdeppe of Germany to do the same thing.
Number of vaulters advancing to the final after clearing 5.70m.
Lane occupied by Usain Bolt as he advanced comfortably to the 100m semi-finals.
Hours between Bolt’s heat and the 100m final Sunday evening.
