Best overall marathon watch

Size: 51 x 51 x 15.6 mm - Battery Life: up to 550 days with solar (battery saver) - Water Resistance: 100m - Memory: 32 GB - Weight: 70g - Screen: MIP - GPS: Yes - Sleep Tracking: Yes - Mobile Payments: Garmin Pay

We're starting off with one of the best Garmin watches on the market - the Garmin Enduro 2. With a name like "Enduro", there's one key area this watch is designed to perform in... its battery life.

Thanks to its solar charging lens, this watch could last up to 550 days when in battery saver mode. Okay, you may not use this mode all the time, but almost two years of charge is something that we just have to mention. Let's say you're using it in GPS mode though, you still get 150 hours of charge with solar, which is great as you'll know it's going to last an entire marathon multiple times over.

In terms of tracking, it's equipped with TopoActive maps, NextFork map guides to provide a detailed map of your route on your wrist, and SatIQ technology to ensure you have precise positional accuracy and detailed route information while you run.

On top of all this, it features built-in sports modes, including "Ultra Run" for long-distance events. In said mode, it can measure your cadence, stride length, and ground contact time, plus it provides a metric that tells you your "running power". Realistically, that's only scratching the surface of what this impressive device can provide. Truly an exceptional smartwatch for marathon training and racing.

2. COROS PACE 2

Best budget marathon watch

Size: 42 x 42 x 11.7 mm - Battery Life: up to 20 days - Water Resistance: 50m - Memory: approximately 200 hours of outdoor workouts - Weight: 35-36g (silicone) / 29-30g (nylon) - Screen: Always-on LCD - GPS: Yes - Sleep Tracking: Yes - Mobile Payments: No

If you're after something a little less expensive though, then the COROS PACE 2 could be the smartwatch for you. It's designed to turn your data into valuable metrics to help improve your performance, making it an excellent running companion during a marathon.

COROS boasts that this particular device is one of the lightest on the market, weighing just 29-30g with its nylon strap. This is to ensure that, even though it packs some heavyweight features, you won't feel weighed down with it on your wrist.

The watch also features what's known as Track Mode, which utilises a proprietary algorithm to ensure accurate measurement of your running sessions and workouts, catering specifically to athletes.

Furthermore, the always-on backlit display proves to be beneficial when you need to quickly glance at your stats during a run. Then, for evening use, the watch offers a Night Mode that dims the screen for enhanced visibility in low-light conditions. Plenty to like then, although if you still have doubts, perhaps the endorsement of Eliud Kipchoge, renowned for his sub-two-hour marathon, will sway your opinion.

Furthermore, it comes with what's known as PacePro, which is designed to keep you on pace with grade-adjusted guidance as you run to ensure your hitting your targets. It also provides a ton of data on your recovery time, heart rate variability, as well as performance stats like your running dynamics and VO2 max.

Its visual race predictor should also come in handy if you're struggling to figure out what pace you need to hit.

In terms of outdoor running metrics, the Ultra provides information on your heart rate, rolling miles, average page, and distance alongside more advanced stats in relation to your running cadence, stride length, ground contact time, vertical oscillation (amount your torso moves vertically with each step).

Frequently asked questions (FAQs)

Don't worry if you've thought of any questions along the way. We've answered some of the most commonly asked queries below to help you out.

What are the key features to look for in a marathon watch?

When buying a marathon watch, there are several key features to look out for. Perhaps the most important of which is a built-in GPS as this allows you to track your distance, pace, and route accurately. It is particularly useful for outdoor running, where you're most likely to run a marathon, and helps you monitor your performance.

You should also look for a device with a long battery life. You'll need something that's going to last for hours when tracking your 26.2-mile run (and that's not even factoring in ultramarathons). As touched on in our list, a watch with a solar charging screen can definitely be helpful here to ensure your device doesn't die mid-race.

You'll probably also want to go for something that's water-resistant. Since running can involve sweat and exposure to the elements, a water-resistant watch is essential. It doesn't have to be fully waterproof, but a 5 ATM rating or above should do the trick.

On top of this, you'll want something that's durable in order to withstand impact, shock, and vibrations, something with an easy-to-read display so you can track your timings and performance quickly while on the move, and something that's comfortable to wear for long periods of time.

Any features beyond this, like built-in marathon-tracking modes and Bluetooth connectivity, are more of a personal preference thing. By looking out for these core features, you should end up with a device that's suitable for marathon training and racing.

Can a marathon watch be used for everyday use?

Yes, a marathon watch can be used for everyday use. While marathon watches are designed to meet the needs of runners specifically, they can also serve as practical and functional timepieces for daily wear as well as other activities like cycling, hiking, and so on. Many marathon watches are designed to be versatile and stylish, and they often come with several key health-tracking features that can be used to track your day-to-day fitness.

The key is to choose a marathon watch that aligns with your personal style preferences and can seamlessly transition from workouts to everyday activities. Consider factors such as the watch's design, size, and strap material to ensure it suits your taste and complements your wardrobe.

In addition to timekeeping, marathon watches often include features like alarms, date displays, and stopwatch functions, which can be useful in everyday life. Some models also offer smartwatch capabilities, allowing you to receive notifications, control music, or even make payments.

Ultimately, the decision to use a marathon watch for everyday wear depends on your personal preferences and lifestyle. If you value a watch that can handle both your fitness pursuits and daily activities, a marathon watch can be a practical choice.

Are marathon watches suitable for indoor running or treadmill workouts?

Yes, they are, but it's important to recognise that many marathon or running watches are designed with outdoor activities in mind. However, some of the key features found in marathon watches can still be beneficial for indoor running or treadmill workouts, depending on your specific needs and preferences.

While built-in GPS functionality may not be as crucial for indoor running, other features like the heart rate monitor and tracking your calories burned can come in handy.

Additionally, some marathon watches offer built-in workout modes specifically tailored for indoor running or treadmill workouts. These modes can provide valuable metrics such as pace and distance, despite running indoors, helping you monitor your progress towards your fitness goals.
