Usain Bolt‘s first 100m race of the season did not sit well with the fastest man of all time.
Bolt won in 10.12 seconds in Rio de Janeiro on Sunday, over U.S. Olympian Ryan Bailey, Netherlands Olympian Churandy Martina and a Brazilian.
“I think it was poor execution overall,” Bolt said, according to Reuters. “I am sure my coach isn’t going to be too happy. The good thing is that I won.”
It’s his slowest recorded 100m time in a finals race. He’s been slower in preliminary heats at major championships, where he could get away with shutting it down early and still advance to the next round.
“My start’s been letting me down, hasn’t been consistent,” Bolt said in a post-race interview. “I just need more runs, and I’ll be OK.”
Bolt was perhaps slowed by faulty starting blocks. Check out the 1:55 mark in this highlight of the race, as one of Bolt’s blocks flew up after he propelled from it.
Bolt, 28, only ran 400 meters total in competition last year, his season starting late due to March foot surgery and ending early as a precaution. In two 100m races last year, his best time was 9.98 seconds. His world record, from 2009, is 9.58.
On April 11, Bolt ran a 200m race in 20.20 seconds in Kingston, Jamaica. That was more in line with his usual early season times for sprints.
Bolt is next expected to race at the IAAF World Relays in Nassau, Bahamas, in May. He could go head-to-head on relay anchor legs with U.S. rival Justin Gatlin, who was the fastest man in the 100m and 200m last year.
Also Sunday, Brazilian TV aired an interview with Bolt (may be geoblocked) where he was asked to pick two sprinters across history he would like to race against. Bolt picked retired 2000 Olympic champion Maurice Greene and, surprisingly, disgraced Canadian sprinter Ben Johnson, who was stripped of a 1988 Olympic 100m gold medal for doping.
The broadcaster then put together a simulation of a potential Bolt-Greene-Johnson race, with Bolt winning in a world record 9.4 seconds.
