In the past, many drivers have attempted to run both the Indy 500 and the Coca Cola 600 on the same day. But recently, no driver has made an attempt at the famous feat.
While Penske Racing driver Will Power led Thursday's session, it was his teammate Helio Castroneves taking the top spot today with a speed of 228.611mph on the day before pole qualifying.
IZOD IndyCar Series Points Leader Will Power topped the charts today with a speed of 227.778 (mph) for the fastest lap of the day and the month so far.
Mike Conway shook down his No. 27 Hire Heroes Car and his Andretti Autosport teammate Marco Andretti got five laps in driving Conway's car, before the rains came ending the session early.
For the second practice day in a row, it's been a surprise a top the standings as Alex Tagliani and Sam Schmidt Motorsports topped the charts with a best lap of 225.878 mph, the quickest of all three days so far.
After missing the field last year, Jay Howard will team up with Sam Schmidt to attempt to qualify for the 100th anniversary running of the Indianapolis 500.
