Sao Paulo - McLaren and two-times Formula One world champion Fernando Alonso will enter next year's Indianapolis 500, the team announced on Saturday.
It will be the second time the Spaniard has taken part in the race, which he led in 2017 before retiring with an engine problem.
The 37-year-old, who is also competing for Toyota in the World Endurance Championship, is leaving Formula One at the end of this season and the May 26 date in Indianapolis will not clash with any commitments.
Alonso is a double Monaco Grand Prix winner and also won the Le Mans 24 Hours this year, leaving only Indianapolis between him and becoming only the second driver to achieve the 'Triple Crown of Motorsport'.
The late Briton Graham Hill, also a two-times Formula One champion and who died in 1975, is the only one to have done it - completing the triple in 1972.
