Race-goers trudging home after a long day at the track may be in for a rude shock with technical issues plaguing ride-share giant Uber.

An image was displayed on screens at Flemington racecourse about 5:30pm saying that "due to a technical fault" with the Uber app, punters would need to seek alternative transport home.

A spokeswoman for the ride-share company confirmed the outage.

"Our priority is transporting people safely and conveniently. We rigorously test all our special event technology, but unfortunately on this occasion technical issues have meant that we are currently unable to connect all drivers and riders at the dedicated Uber zones within the Flemington Racecourse," she said.

"We appreciate this has been frustrating for many of our valued riders and driver-partners, and we apologise for the inconvenience this has caused."

Uber announced earnings Monday that beat analyst estimates on the top and bottom lines for its third quarter of 2019. But the stock fell as much about 5 per cent after the company reported more than $1 billion in net losses.

The Victorian Racing Club released a statement on Twitter saying that "technical issues have meant that Uber is currently unable to connect drivers and riders within Flemington Racecourse."
