As usual for my anime reviews, this is copied from the season 1 comments. This series might get a second season—the producer expressed interest in making one—and if that happens I will update this review if/when I watch that second season.
Average episode rating for season one: 6.61538462
This is another time that I won't round the rating up even though, mathematically, it deserves to be. Even though the series is enjoyable to watch, I wouldn't really call it "Good". The pacing is much too fast, and I never felt there were any real stakes to the story. It never seemed like Special Week really might not reach her goal; she just had minor setbacks. Silence Suzuka had a slightly better character arc, but it was no less predictable along the way.
I like to think this show could have been better in two cours. On the one hand, sports anime are not one of my preferred genres, in general. A two-cour anime about a sport I know nothing about would have been intimidating, and I probably wouldn't have started it on an impulse like I did. But the extra length would have allowed for more leisurely pacing that allowed time to show the girls' training work instead of focusing on races and rarely showing the long stretches of practice in between.
A longer series would have also let the audience get better acquainted with the characters. If your anime needs to put name cards on screen every time a character appears to make sure we remember who they are, you've either got too many characters or not enough time to introduce them all. Or both.
