Olympic,Sportsbook.com,Pinny and Wagerweb provide a good array of lines and wagers.Its best to check many sites because in contrast to most sportbetting the odds can vary largely for the same bet.Lines to win come out Tuesday/Wednesdays....props,matchups ,top3,etc come out the day of the race normally.Some folks bet them early to get a better line than the one they might get when practice/qualifyings over.I always will wait till the day of the race.
