Query execution time

I have a query that has been executed 750,000 times and want to know what the maximum elapsed time is for that query. The v$sql view gives me an elapsed_time column, but that will only allow me to produce an average elapsed time based on the number of times a query has been executed. Is there a way to determine the maximum elapsed time for a query?  

Thanks,
