Fernando Alonso has been trying to complete motorsport's 'triple crown'
Fernando Alonso has failed to qualify for the Indianapolis 500 after a humiliating return to the USA's biggest race for the McLaren team.
The two-time Formula 1 world champion was fourth fastest of six drivers vying for the final three places on the grid on what is known as 'Bump Day'.
Alonso's 227.353mph four-lap average was pipped by American Kyle Kaiser by just 0.019mph with the last run.
It is a bitter blow for Alonso, who left F1 to focus on winning Indy.
"A difficult week, no doubts," Alonso said on social media. "We tried our best, even today with a completely different set up and approach, four laps flat on the throttle but we were not fast enough.
"It's never easy to drive around here at 227mph+, and want more speed... We tried our best and we've been brave at times, but there were people doing better job than us.
"Success or disappointments only come if you accept big challenges. We accepted. Thanks to the massive support always here at the speedway and everyone at home."
