Here’s how your speed compares to others who played this game:

Reaction times over 2 seconds are excluded from this data.

If you’re upset that this competition is unfair, well, you may be right. Usain Bolt is the world’s fastest man. You, on the other hand, are just ears and a thumb as far as this quiz is concerned. But if there were a (short) list of speed-related things you could beat Usain Bolt at, his reaction time would be near the top.

In the 100-meter final in Rio on Sunday night, six of Bolt’s seven opponents reacted faster than he did:

Name Country Reaction Time Reaction Rank Final Time Final Place Akani Simbine South Africa 0.128 1 9.94 5 Trayvon Bromell United States 0.135 2 10.06 8 Jimmy Vicaut France 0.140 3 10.04 7 Andre de Grasse Canada 0.141 4 9.91 3 Yohan Blake Jamaica 0.145 5 9.93 4 Justin Gatlin United States 0.152 6 9.89 2 Usain Bolt Jamaica 0.155 7 9.81 1 Ben Youssef Meite Ivory Coast 0.156 8 9.96 6

But being faster out of the blocks wasn’t enough for those athletes: Bolt still won by eight hundredths of a second.

Guessing when the starting gun is going to fire won’t help you either. Any reaction time less than one-tenth of a second is considered a false start, and there are no second chances. In 2011, Bolt had a false start at the world championships and was immediately disqualified, a blemish on his otherwise perfect run of world championship golds from 2009 to 2015.

That disqualification meant Bolt couldn’t defend his gold medal performance from 2009 in Berlin, when he set the world record, finishing in a blistering 9.58 seconds. With Bolt disqualified, Yohan Blake, a fellow Jamaican, took Bolt’s place atop the podium.
