# Thoroughbred Aftercare Alliance Stakes

The Thoroughbred Aftercare Alliance Stakes is a ungraded American Thoroughbred horse race for two year olds over a distance of one mile on the turf. Previously, the event was a Grade II event for three-year-olds and up, and contested on dirt usually at a distance of 1+5⁄8 miles. The race has a purse of US$200,000. It is run as part of the undercard on either the Friday card or Saturday card of the Breeders' Cup.

## Race history

The race was originally established in 2008 as part of the annual Breeders' Cup World Championships with its inaugural running on October 25, 2008 at a distance of 1+1⁄2 miles as the Breeders' Cup Marathon. The inaugural running took place on the second day of the Breeders' Cup on the Pro-Ride synthetic dirt at the 2008 host track, Santa Anita Park in Arcadia, California.
In 2009, the distance was extended by 2 furlongs to 1+3⁄4 miles.
Due to technical requirements, the race was not eligible for classification as a graded stakes race in its first two runnings. It received Grade III status effective in 2010. The race was upgraded to Grade II status for 2011. The race was originally run under Weight for Age conditions.

### Removal from Breeders' Cup

On April 25, 2014, the Breeders' Cup announced that the Marathon would be discontinued. The event was renamed to the Marathon Stakes as an undercard Breeders' Cup stakes race. The purse of the event was reduced from $500,000 to $200,000. The first year, the race was sponsored by the Las Vegas Tourism Board. The event's conditions were changed to Set Weights with allowances.
Citing that "the conditions of the race have not developed into a competition that we believe reaches the standard set by the remaining races comprising the Championships", the Breeders' Cup Committee announced its discontinuation.
However, the venue that holds the Breeders' Cup has been running the event with separate sponsorship.
In 2020 the event was renamed to the Thoroughbred Aftercare Alliance Stakes, sponsors since 2017.
In 2024 the event was downgraded by the Thoroughbred Owners and Breeders Association to Grade III status. However, the Breeders' Cup undercard changed the conditions of the event from a Marathon distance for older horses to a two-year-old turf event over one mile. The event was run as an ungraded black-type event.
