Who will win men's 110m hurdles?
KC Graham: No one has set the place on fire this season in the men's 110 metres hurdles. This is one event where a favourite cannot be identified, despite the defending champion, David Oliver, being in the event.
Andre Lowe: Indeed. There were some good early showings from Aleec Harris, but he has lost his way since June. Now it's anybody's race. it's really difficult to pick a winner here, and that's what makes this one of the events of the championships.
KC: With the Cuban, Orlando Ortega, not competing, this has even made it more complexed, as he was the most consistent of the lot, and this is another event where the top-ranked athlete will be missing.
Andre: Jamaica have two really good hurdlers in Omar McLeod and Hansle Parchment, who, on the day, can top any field in the world, and Andrew Riley, who is solid at 13.3 or thereabouts. That range won't get him close enough.
KC: Of the three, I think only McLeod and Parchment have realistic chances of medalling, as both have gone sub-13 seconds already in their career, and if both rediscover their form, it could be history for Jamaica once again in a different discipline.
Andre: I agree. Parchment's power and speed between the hurdles make him a real threat, but he hasn't raced a lot, and that's important in the hurdles for rhythm. McLeod is the real deal; he's medalling here for sure. As long as he keeps it simple, there's no way three athletes beat him.
KC: McLeod is the best technically of all the athletes in the event. I can tell you this, no one can lead him to the first three hurdles, and if he has recovered fully from his minor injury in his first pro race, he will not be caught. His experience in the 400 metres hurdles will give him an edge here, too, as he also has good speed endurance.
Andre: I like McLeod for the win, but only if he's close to full fitness. I haven't heard anything to suggest that he isn't. It's a brave pick, but I'm also going with Parchment, who does well under pressure and knows he needs to come good after some poor decision making. He will battle for third, I think, with a few, including Sergey Shubenkov and Pascal Martinet- Lagarde. He needs a big performance, and it is coming here as well. So two Jamaicans to medal, with Oliver in the mix as well.
KC: While I think the strong and powerful Oliver will be the favourite for the gold here, I think McLeod and the Russian, Shubenkov, are big dangers. I will give the American the edge to make it back-to-back titles, and I agree with you that McLeod will be among the medals here. I don't like Pascal's technique; he seems to be running on the spot of late.
