And it came in a big race in Japan - the national Women's Ekiden which sounds amazing.

In many ways this year's National Women's Ekiden showed exactly what is great about the interprefectural format, one of the only places where the top runners from different levels of the Japanese system face off. On the 6.0 km First Stage Kagoshima Joshi H.S. junior Miyuki Uehara (Kagoshima), with a 9:06.91 best for 3000 m and a long, loping stride atypical among Japanese distance runners, took the race out fast, quickly shaking it down to a lead trio of herself, pro Rei Ohara (Okayama/Team Tenmaya) and collegiate Ayuko Suzuki (Aichi/Nagoya Univ.). A top high schooler, a top collegiate and a top pro. Exactly what makes the men's and women's interprefectural ekidens such an entertaining watch. Especially when the high schooler turns it on and opens 11 seconds over the last 500 m and just misses the course record. And beats an Olympic marathoner by 27 seconds, as she did to Ryoko Kizaki (Osaka/Team Daihatsu).
Miyuki Uehara is 17 years old and 5+ months older (163 days) older than Mary Cain. She's 3 times run under 9:10 for 3000 on the track and has a 9:06.91 pb. She was 8th at world jrs last year and 3rd at the Japanese HS champs (two kenyans beat here).
