As of August 2015, you can view Daily Racing Form results on the DRF website or in the print edition of DRF. On the DRF results page, the default view lists all of the U.S. horse racing tracks that held races on the current day.
You can view results for any day within the last month. After choosing a desired day, click on a particular track. All the races held at that track on that day are shown. You can also click directly on a particular race number.
DRF started publishing in 1894. DRF provides past performance results and other information that is useful to horse racing bettors.
