Marathonbet Review

Established in 1997, Marathonbet is one of the more well-known online bookmakers to come out of the United Kingdom. They first set up their online betting platform in 2002, becoming one of the first online sportsbook options in the process.

This Marathonbet review will take an in-depth look at the overall service this sports betting site offers to its customers, such as the range of sports on offer, the various betting promotions that can be accessed, and their site’s overall structure.

Welcome Offer & Bonus

It is rare that you won’t have the option to claim a welcome offer when you sign up to a new online sportsbook. These types of offers have become industry standard in recent times, and Marathonbet have their own. Like many others, it is a deposit bonus that sees players who sign up and deposit £20 rewarded with a £20 free bet to use. To claim this free bet, you will need to turn over your initial deposit amount five times at minimum odds of 1/2 or greater and sign up using the promo code ‘MBW20’. Additional deposits may be required in order to fulfil the turnover conditions, which must be met within 90 days of depositing. A £20 free bet is certainly an enticing dangling carrot, although the lengths with which players must go to in order to achieve it hurts this offer when compared to other welcome bonuses. There are plenty of other ‘Bet X Get X’ offers out there, although they often don’t require a turnover requirement before you get the free bet.

Pros & Cons

Markets & Betting Options

Having a wide range of sports betting markets to bet on can hugely improve the overall customer experience. There is no shortage of sports markets at Marathonbet, which boast both niche and popular markets as part of their portfolio of options. The complete list of available sports to wager on at Marathonbet include: Alpine Skiing, American Football, Aussie Rules, Autosport, Badminton, Bandy, Baseball (more about baseball betting sites), Basketball, Basketball 3×3, Biathlon, Bowls, Boxing, Chess, Cricket, Cycling, Darts, e-Sports, Floorball, Football, Golf, Greyhounds, Handball, Horse Racing, Ice Hockey, Lottery, MMA, Rugby League, Rugby Union, Snooker, Specials, Table Tennis, Tennis, Volleyball and Water Polo.

A wide variety of betting markets could match many other offerings from rival online sportsbooks. Those who sign up can always be guaranteed to have something to bet on when they create an account with Marathonbet. You can also find a range of betting options when it comes to single events too, with a vast number of individual markets available within each event that you find. However, they have yet to add a bet builder-type function onto their site, which has proven to be extremely popular elsewhere.

Our Scores






Live Betting & In-Play

You can find all of the in-play events at Marathonbet under the ‘Live’ tab at the top of the home page. For those who don’t know, in-play betting is where punters will place wagers on events after they have already begun. Increases in technology now mean that this is a widespread feature seen across multiple betting websites. The vast majority of big-name bookies are now using the betting feature.

These also come with a variety of sports, with there being in-play events for each of the following sports at the time of writing: Football, Horse Racing, Tennis, Basketball, Ice Hockey, Snooker, Volleyball, Bowls, Greyhounds, Table Tennis and eSports. Many enjoy placing in-play bets as they add excitement to live events, particularly if you are watching or streaming them live. It can also help players get bigger odds on selections compared to what they would’ve done pre-game, although this can work the other way too. Marathonbet’s in-play betting service is extremely accomplished.

Ongoing Promotions & Offers

In addition to the welcome offer, Marathonbet also has a range of available promotions for existing customers. They are particularly good when it comes to horse racing promotions, with Best Odds Guaranteed being the leading offer. This means if you back a winning horse at a lower price than the SP, you will still be paid out the larger amount. The Double Result offer also sees Marathonbet payout on both results on a horse race if the winner is disqualified.

Another popular existing customer promotion is Acca Insurance. This means if your accumulator (minimum five selections) is let down by just one leg, Marathonbet will refund your 100% of your stake in the shape of a free bet up to £30. Similarly, Bore Draw ensures that players who bet on the final score of a football match that eventually finishes 0-0 are refunded in the shape of a free bet of up to £30.

VIP Promotion & Player Rewards

Marathonbet runs a loyalty program that acts as the equivalent to their VIP program. Sports, casino and live casino bets all count towards their loyalty program, with qualifying sports needing to have a stake of at least 10p and have odds of at least 1.30 or greater. Loyalty points for each time you play at Marathonbet are only counted towards your total on sports bets once your bet has settled. The Marathonbet loyalty program allows you to take advantage of all the benefits of the bonus catalogue in exchange for the points accumulated for your bets. This is a program that is best suited towards high roller players over casual players, allowing the former to earn additional bonuses in exchange for their higher level of play.

Casino, Slots & Bingo At Marathonbet

As well as their sportsbook, Marathonbet also has an online casino for their customers to use. This comes with a variety of casino betting options and classic casino games for players to turn their hands to. This includes a variety of dealer games such as roulette, blackjack and poker, while they also have a number of slot games for their users to take advantage of. Their slot title collection isn’t the most impressive that we have seen when it comes to some of the biggest and best games out there but does include: Fire Joker, Riche Wilde, Avatars Gateway Guardians, Lightning Joker and Reel Gems. Unfortunately, there is no offering of bingo games at Marathonbet.

Play on Mobile & Marathonbet App

The Marathonbet app was launched in 2013 and is available for Android, iOS and tablet devices. We must admit that we didn’t particularly enjoy our time using the Marathonbet, and it looked pretty outdated compared to some of the competition out there. It also wasn’t as fast or responsive as other gambling mobile apps that we have seen and could really do with some major improvements in the near future. They also have a mobile-friendly website that can be accessed through your device’s web browser, which is presented in a similar manner to the desktop version of the site. Aesthetically, both look outdated and are plagued by awful designs that pale compared to some of their competitors in the space.

Payment Methods & Depositing

There are 12 different payment methods that can be used at Marathonbet that can all be used to add funds to your account. Some of the most popular deposit method options include: Skrill, Neteller, PayPal (more about Paypal betting sites here) PaySafeCard, ecoPayz, Mastercard, VISA, Bank Transfer and Apple Pay. A minimum deposit amount of £5 is required every time you are looking to add funds to your Marathonbet account. Be sure to read the terms and conditions of all deposit bonuses that you claim with any bookmaker to ensure that your preferred payment option is eligible for that particular bonus. When it comes to withdrawals, they are renowned for their quick payouts and put no monthly withdrawal limits on players’ accounts. 

Is Marathonbet Trustworthy?

Many will trust Marathonbet thanks to the brand recognition that has come from their various sponsorship deals with each of the following European football clubs:  Manchester Utd, Liverpool, Tottenham Hotspur, West Ham, Fulham, Middlesbrough, Derby County, Hibernian, Lazio, Sevilla, Malaga, Girona, Dynamo Moscow and FC Karpaty Lviv. However, your trust should really be secured by the gambling license they have been awarded from the United Kingdom Gambling Commission. This lets customers know that all of Marathonbet’s operations are regulated by one of the most respected gambling authorities with the industry. You should only ever gamble online with licensed operators, and Marathonbet fit the bill.

Customer Support

Should you require assistance at any stage of your journey with Marathonbet, their customer support service will be on hand to aid you. The best option is their live chat service, which allows you to speak directly to a customer support representative via messenger. This will generally allow you to get the quickest resolution possible. UK residents can call them on 0800 9757882, while non-UK residents can call +44 1273 964705. Three different email addresses can be contacted depending on the topic of your query: (general), (deposits and withdrawals) and (gambling concerns).

Language Support

There is also the option for users to choose between four different languages on-site at Marathonbet: English, French, German and Slovenian. The same applies to all customer support options except for live chat.

Marathonbet Summary

There is plenty to like about Marathonbet, albeit with some improvements that can be made. One of the main things is the design of the website and app, both of which look outdated and very basic when compared to the graphics used for other bookmakers. That said, they have some strong offers and promotions for customers to claim and a strong range of markets. Today, those who create an account with Marathonbet can get their hands on a £20 free bet as part of the welcome offer.
