IAAF / World Athletics, with ATFS — Birmingham 2018 Statistics Handbook — selected indoor record snapshots and championship heat results ↗

Publication date: 2018

Selected from the handbook's best national placings table: 5h1 means 5 in heat 1, not 5 overall and not a medal. Mark and year belong to that championship heat. Exact day, venue and timing method are not independently curated. Country-best heat placing is not a fastest-time record.

primary-source

Selected independently structured sporting facts only. Extracted tables checked against rendered samples and headings. No complete results book, source prose, images or pages republished. Historical national-record snapshot is not live ratification or complete progression. No blanket commercial redistribution licence established.
