Indy 500 faces record heat

The Indianapolis 500 could set a track record for heat during this year’s race. Weather forecasts say it could reach 94 degrees during Sunday’s race with a 100-degree heat index, which factors in humidity. That would break the previous race-day record of 92 degrees set in 1937. The Indianapolis Motor Speedway said it will use cooling fans and misting stations to help fans stay cool. The speedway medical staff expects to treat more than 1,000 people for heat-related illness on race day.
