Elaine Thompson won a 100m at her first meet since sweeping the Olympic sprints, but she actually raced about 200 meters in Lausanne, Switzerland, on Thursday.
Thompson, who won the 100m and 200m in her Olympic debut in Rio, was one of seven runners in an eight-woman 100m field in Lausanne who did not react to a second gun indicating a false start.
So Thompson and others had to trudge back from the finish line to the start in order to re-run the race.
About nine minutes after the false start, Thompson won the 100m in 10.78 seconds (video here), a bit slower than her national record-matching 10.70 from the Jamaican Olympic Trials and her 10.71 from the Rio Games.
“There was a mix up at the start,” Thompson said, according to the IAAF. “To be able to produce 10.79 [sic] on second attempt, it’s a great time.”
Neither of the other Rio Olympic 100m medalists — Tori Bowie or Shelly-Ann Fraser-Pryce — was in the Lausanne field.
Untested, Thompson won by one-third of a second over American Jenna Prandini.

In other events Thursday, former world-record holder Asafa Powell won the 100m in 9.96 seconds against a field that didn’t include Rio medalists Usain Bolt, Justin Gatlin or Andre De Grasse. Powell, 33, broke 10 seconds for a record 97th time, according to the IAAF.
Rio bronze medalist LaShawn Merritt won a 400m in 44.50 against a field that did not include the Olympic gold and silver medalists Wayde van Niekerk and Kirani James. Van Niekerk won the Olympic title in a world record 43.03.
Keni Harrison, who missed the U.S. Olympic team but broke the 100m hurdles world record July 22, won the Lausanne 100m hurdles in 12.42 seconds. The field did not include the Americans who swept the Olympic podium — Brianna Rollins, Nia Ali and Kristi Castlin.
Harrison’s time Thursday would have won the Rio Olympics and was well short of her world record of 12.20.
“I’m a bit rusty because I haven’t competed for a few weeks with not being in Rio,” Harrison said.
American Dalilah Muhammad followed her Olympic 400m hurdles title with her second straight Diamond League race victory, clocking 53.78 in Lausanne.
Cuban-born Spaniard Orlando Ortega upset Olympic champion Omar McLeod of Jamaica in the 110m hurdles, winning by one hundredth of a second in 13.11. Ortega took silver behind McLeod in Rio.
In the shot put, New Zealand’s Valerie Adams topped Michelle Carter, also a reversal of their Rio Olympic one-two. Adams, the 2012 Olympic champion, threw 19.94 meters in Lausanne, while Carter recorded 19.49 meters.
Olympic bronze medalist Sam Kendricks equaled his personal best with a 5.92-meter clearance to win the pole vault over world-record holder Renaud Lavillenie. Surprise Olympic champion Thiago Braz da Silva of Brazil wasn’t in the Lausanne field.
The Diamond League continues in Paris on Saturday.
