Need help looking for this doujin

Hi,

so the doujin is about the school track team and the main guy is this non athletic guy but never gives up and he has a crush on the the girl ace and they have a tradition in the club of no relationships but also this other tradition that rewards(sex) hard workers I think or maybe its to compensate the no dating rule or both but i cant remember forsure and thats about it. if anyone can help me that'd be awesome. Thanks
