Briana Williams ran five races at the AP High-Performance Invitationals 1-5 in Fort Worth, Texas earlier today, a meet at which American Michael Norman ran a world-leading 9.86 in the 100m.

Some of the world’s best athletes, most of them Nike-sponsored, descended on Fort Worth to compete, reportedly in a bid to preserve the value of their professional contracts.

According to sources, under the terms of their contracts, the athletes are obligated to compete in at least 10 sanctioned races for the year. If they do not, they stand to lose money from their multi-million-dollar contracts.

In response, meets were created, the first of which was held today, that will allow the athletes to fulfil those obligations and as a result, save themselves millions of dollars.

Williams, who earlier this year signed a five-year contract with Nike believed to be valued at several million dollars, competed in the 60m, 100m, 150m, 250 and 300m races. She clocked 7.68 for the 60m, 12.43 for the 100m, 18.74 for the 150m, 38.31 over 250 and 46.56 for 300m.

Norman ran 7.96 for the 60m, 9.86 for the 100m, 34.82 for the 250 and 44.90 for 300m. His 100m time puts him in a pantheon of two, the number of athletes who would have run sub-10s, sub-20 for the 200m and sub-44 for the 400m.

Justin Gatlin, the 2017 100m World 100m champion, also competed at the meet setting times of 6.84 for 60m, 10.84 for the 100m, 15.93 for 150m, 32.53 for 250m and 42.32 for 300m.

In the men’s 100m, 400m hurdler Rai Benjamin ran an impressive 10.03 a massive personal best for the World Championship silver medallist. Ronnie Baker of the USA was third in 10.23.
