Watched live-stream of Irena Szewinska Memorial - Bydgoszcs (Poland).
Though I was aware of Christine Mboma from Nambia, it's the first time I saw her in action in the women's 400m. She's 18 yrs old, and has a 22.67 PB in 200m this year.
She just ran, no, fly(!) through the track to 48.54, a 400m WJR and the 7th all time behind such luminaries as:
Marita Koch (47.60, 6th Oct 1985)
Jarmila Kratochvilova (47.99, 10th Aug 1983)
Salwa Eid Naser (48.14, 3rd Oct 2019)
Marie-José Perec (48.25, 29th July 1996)
Olga Bryzgina (48.27, 6th Oct 1985)
Shaunae Miller-Uibo (48.37, 3rd Oct 2019)
Mboma & the other women did not run in good condition - it was very windy. Could have lowered her time a lot. She's about 30m ahead of Swiety, a good basic 50sec runner. Now look at Koch's 47.60 time and compare the distance between Koch's 47.60, Mboma's 48.54 and Swiety's 51.91 - there's no way that any normal woman could run Koch's time without the assistance of a full blown steroid regime. I don't believe that Mboma could break that record but she could approach it. Koch was an exceptional sprinter who doesn't need to dope - she was a youth prodigy. You can discount Koch & Kratochvilova times as they're likely on a seriously heavy steroid regime being administered by the then East Germany's sport program as likely for Bryzgina for the then USSR.
Naser, (more like careless on her part) missed 3 drug tests. So it's just the three ladies - Naser (maybe), Perec & Miller-Uibo who're ahead of Mboma.
Mboma can either become a phenom, or drop off the map. I would like her to battle Athing Mu. Pity that Mu concentrated on 800m instead of 400m. At the moment Mboma has more speed than Mu and is a scary thing to witness on the track since Bolt. lol
