As we begin the countdown from 100 days, we take a look back at some of the best 100m races from the 2015 IAAF Diamond League season.
Usain Bolt silences critics
With the whole world questioning his form, Bolt silenced his critics at last year's Sainsbury's Anniversay Games. In both the heat and the final, he ran 9.87 – a bullish rebuke to all those who thought he might have lost his touch. His Diamond League triumph was a defiant comeback which paved the way for his victory at the World Championships in Beijing a month later.
Dafne Schippers soars in London
Another memorable moment from the London leg of last year's Diamond League: Dafne Schippers launched a triumphant summer with victory in the women's 100m final. Surging forward from the back, the Dutch sprint star raced past the likes of Murielle Ahoure, Dina Asher-Smith and Blessing Okagbare to snatch victory.
Shelly-Ann Fraser-Pryce rules in Paris
In a season which eventually saw her take both the Diamond Trophy and gold at theWorld Championships, Fraser-Pryce had started slowly in the Diamond Race. At Paris on July 4, however, she burst away from the rest of the field to take a convincing victory and take the lead in the standings. It was the start of an unrelenting drive to Diamond Race glory, as she followed her Paris triumph with victories in Stockholm and Zürich.
