Letesenbet Gidey 29.01 is 1303 on Athletics points scoring system. Her Road World record 15K 44.20 Athletics points scoring system is 1319, higher. No spikes were used for this Road race, or indeed wave lights. This woman is just very good is the real answer. In fact her 1319 points is the best track female score ever in history. Flo Jo's was 1314. So again Letesenbet is just very good and lives at altitude is another benefit.
So next question how can she run 14. 18 2nd Half negative split of 10,000 meters World Record. Is easy for her, as has 5000 meters world record 14.06secs, and is 2nd half of the race she is, strongest at. Enjoy, I will watching the Olympics.
