The men's 100 metres will be one of the main attractions as the final Diamond League event of the season takes place in Brussels on Friday.
American Michael Rodgers leads the points standings heading into the final race of the year on nine points, but fellow countryman Justin Gatlin is on eight points, with Jamaican Nesta Carter one further back.
All three will be racing in the Belgian capital, with Gatlin perhaps the biggest threat to Rodgers' chances of claiming the title.
Gatlin, the world silver medalist from 2013, won the first two Diamond League races of the year, but a few little injuries has allowed Rodgers to replace him at the top of the points table.
If he can get anywhere near his season's best, though - a world-lead time of 9.80 seconds, he will surely have enough to take the victory, and the title.
The other syand-out races of the night include the women's 200m and the men's high jump.
In the 200m, all-conquering Dutch athlete Dafne Schippers will be hoping to continue her excellent recent form as she takes on Blessing Okagbare and Allyson Felix.
Schippers, the European 100m and 200m champion, ran a world-leading time of 22.03 seconds to take gold in Zurich, and has beaten her two rivals already this season.
Felix and Okagbare both have chances to win the overall points race, though, and will be looking to avenge their previous defeat.
The men's high jump has perhaps been the highest standard event of the year and, although Ukraine's Bohdan Bondarenko has a four point lead at the top of the standings, the meet still promises to be an enthralling one, as the 2014 Diamond League draws to a close.
