Outkicked other Kenyan transferee Yasemin Can (multiple "european" champion), who ran under 14:40 last year. So far this year that's #7 in the world and I bet she could run in the 14:30's in a faster race. But then again Klosterhalfen also ran 14:51 by herself and I bet she could also run faster, especially in a race where she's not running the whole thing alone (also did that running 4:04 at German indoors this year). Amazingly all 3 of them are only 20.
