The professional track and field circuit that began in May in Doha comes to an end this week. Thursday and Friday's Diamond League finals in Zurich and Brussels will be the last time we see many of the top names in the sport this year. The next time they make an appearance, new questions and storylines will emerge as the focus zooms in on the 2019 IAAF World Championships in Doha. 

But for now, this week leaves athletes one last chance to make an impression on 2018-- one last chance to set a world lead, season-best or to settle a rivalry. And it's also the last chance for confidence picks!
