Horse Racing Free Bets for the Prix de l’Arc de Triomphe on Sunday October 4th

October 4, 2026
par Emma Harrison

One of Europe’s biggest horse racing events returns this Sunday: Prix de l’Arc de Triomphe. Daryz is the betting favourite as he looks to defend his title, but riders like Maltese Cross and Kalpana will bring stiff competition.

Want to get involved? Horse racing free bets are a great way to have your say. Betfred is offering £50 in free bets when you bet £10 on sports, while bet365 has £30 in free bets up for grabs before the big race. Even BetMGM is saddling up with a £40 offer. Keep reading as we reveal the details.

Get your hooves into these Prix de l’Arc de Triomphe free bets

UK betting sites like Betfred, bet365, and BetMGM will certainly bring plenty to the starting gate this weekend. In preparation for the Prix de l’Arc de Triomphe, they’re each trotting out generous free bet bonuses. Here’s what to expect:

Betfred – £50 in free bets

On paper, the Betfred free bets bonus is the biggest runner in the Prix de l’Arc de Triomphe. When you register with our link, deposit and bet £10 on odds of 2.0 or greater, you’ll get £50 in free bets. There’s a catch, though: the bonus is split into £30 for any sport and £20 for Bet Builders. That’s not such a big issue anyway, since both can be used on horse racing markets.

And this welcome package isn’t the only horse that Betfred has in the race. Place a win or each-way single after 08:00, and if your selection finishes second, your stake is refunded up to £10 in free bets.

bet365 – £30 in free bets

bet365 : Avantages et inconvénients
  • Plusieurs sections, dont les paris sportifs, les jeux de casino, le bingo et les sports électroniques.
  • L'une des meilleures applications mobiles disponibles pour Android et iOS
  • De superbes options de paris pour les joueurs et les parieurs pour les paris sportifs.
  • Site web facile à utiliser avec une navigation primaire simple
  • La limite de dépôt minimum de PayPal pourrait être abaissée à 25€.
Visitez Bet365

The bet365 free bets bonus is the smallest on this list, offering £30 in free bets. But it’s also the most flexible. The qualifying bet has a lower minimum odds requirement of 1.20, and the full £30 in free bets are available for any sports markets, including Prix de l’Arc de Triomphe. There aren’t even any wagering requirements on your winnings.

This sportsbook also offers live streaming, so you can watch and bet from one screen. And with the big race still a few days out, there’s a decent chance even more UK betting promotions will join the starting line-up, including odds boost markets.

BetMGM – £40 in free bets

BetMGM : Avantages et inconvénients
  • L'une des meilleures applications mobiles disponibles pour les sites britanniques
  • Grande variété de méthodes de paiement
  • Délais de traitement des dépôts et des retraits instantanés
  • Vaste gamme de jeux de casino, y compris des croupiers en direct
  • Peu de promotions pour les clients existants
Visitez BetMGM UK

Last but not least: the BetMGM free bets bonus. To opt in, just register with our link, deposit, and settle a £10 bet at odds of 2.0 or higher. Again, the free bets you receive here are split into two £10 sports multiples and two £10 football accumulators.

That means you’ll technically only have £20 for horse racing multiples to use on the Prix de l’Arc de Triomphe. But that might be more suitable if you’re a bettor who prefers variety. BetMGM is also a great all-around sportsbook, so we’re sure you’ll have a blast here. We’re talking a native mobile app, 24/7 support, and a wide selection of payment methods.

Which free bet offer makes it to the finish line this weekend?

Betfred seems like the best option for the Prix de l’Arc de Triomphe this weekend, given its £50 in free bets. But things aren’t that black and white. bet365 still offers a competitive £30 in free bets, with terms that are much more flexible. Then there’s BetMGM with £40 in free bets, although just like Betfred, its rewards must be used on a narrower set of markets.

But the power is fully in your hands. Which sportsbook gets your vote? You can use any of our links on this page to get started with one of these welcome packages today.
