Nozomi Tanaka, age 24. Insane improvement from this Japanese athlete over the past few years from relative obscurity to super elite world class. She was hovering around 15 minutes just a couple of years ago (and 32:+/10,000), and now she's down to 14:29.18, finishing 3rd in Brussels tonight (hot conditions).
How far will her ceiling take her? Sub 14:20 next year? Can she challenge Hassan, Gidey, Taye, et Al?
