Running Accessories

The right running accessories make the difference between a run where you are distracted by practical problems and a training session where you can fully focus on your performance. A well-fitting hip bag keeps your phone, keys and gels within reach without bouncing. A waterproof phone case protects your smartphone in rain or during open water swimming. A water bottle keeps you hydrated over longer distances. Small additions, big impact.

The range runs from compact pocket belts for a key and phone to more extensive hip bags for marathon and triathlon training, waterproof phone cases for use in rain and open water and water bottles for use in combination with a hydration belt or hip bag. The main selection criteria are the carrying comfort and stability when running, the storage capacity and the water resistance of the chosen product. Also view our complete range of hydration belts for extensive hydration solutions during longer runs.

Which running accessory do you need?

The right choice depends on the distance you run, what you want to take along and the conditions in which you train. The following scenarios help you quickly find the right direction.

You want to take your phone, keys and a bank card without a large bag: A compact pocket belt or running belt is the most practical solution. Models such as the Nathan Zipster 2.0 and Nathan 5K Pak Belt are lightweight, fit snugly around your waist and barely move during running. Ideal for training sessions up to 10 kilometres where you want to carry little with you.

You run longer distances and also want to take energy gels and extra things: Choose a more extensive hip bag such as the Nathan Pinnacle Belt or Nathan Marathon Pak 2.0. These offer more storage space for gels, snacks, an extra clothing layer and your smartphone, distributed across multiple compartments for a balanced weight distribution.

You train in rain or do triathlon and want to waterproof protect your phone: A waterproof phone case is indispensable. The BTTLNS Iscariot 1.0 offers basic protection against rain and splash water. The BTTLNS Endymion 1.0 is floating and waterproof, ideal for use during open water swimming or intensive rain. This way you always keep your phone with you without risk of water damage.

You want to take a water bottle for hydration on shorter distances: Compact water bottles of 500ml or 750ml fit in most hip bags and running belts. The BTTLNS Panta 1.0 and BTTLNS Flux 2.0 are light, leak-proof and easy to open while running. For greater hydration needs also view our range of running backpacks with hydration system.

You want to carry your smartphone on your arm for navigation or music: A phone armband keeps your smartphone stable on your upper arm so the screen is always in view. Handy when you navigate on an unknown route or want to control your music without opening your hip bag. Also view our range of sports headphones if you also want to listen to wireless music while running.

What types of running accessories are there?

Hip bags and running belts

Hip bags and running belts are the most used running accessories for carrying essentials during a run. Compact pocket belts are suitable for a phone, keys and a bank card for shorter training sessions. More extensive running belts with multiple compartments are suitable for longer distances where you also want to take gels, a water bottle and extra things. Choose a model of stretch material that fits snugly around your hips and does not move during running.

Waterproof phone cases

Waterproof phone cases protect your smartphone in rain, sweat and open water. Standard waterproof cases protect against splash water and rain. Floating waterproof cases such as the BTTLNS Endymion 1.0 are specially designed for use during open water swimming and triathlon, where your phone does not get lost if it falls out of your hand. Always check whether the case is compatible with your smartphone size.

Phone armbands

A phone armband keeps your smartphone stable on your upper arm. Handy for navigation on unknown routes or controlling music and training apps without breaking stride. Choose an armband with an adjustable fastening that fits the circumference of your upper arm and is compatible with your smartphone size.

Water bottles for running

Compact running water bottles of 500ml to 750ml are designed for use in a hip bag or running belt. Light, leak-proof and easy to open with one hand while running. Ideal for training sessions up to 15 kilometres where you want a supplement to your hydration belt or prefer to run with a loose bottle in your bag.

What to look for when buying?

Fit and stability

The most critical criterion with hip bags and running belts is that they remain stable while running. A bag that bounces up and down or shifts to one side causes irritation and distraction. Preferably choose a model of stretch material that fits snugly around your hips. Set the size correctly so the bag cannot shift but also does not pinch.

Storage capacity

Determine in advance what you want to take along. For a key and phone a compact pocket belt is sufficient. For marathon and triathlon training where you also want to take gels, a water bottle and extra clothing choose a more extensive hip bag with multiple compartments and a larger total capacity.

Water resistance

Do you train in rain or do you do triathlon? Then check whether your hip bag and phone case are water-resistant or waterproof. For rain water-repellent material is sufficient. For open water swimming you need a fully waterproof phone case.

Weight and material

The lighter the bag the less you notice it while running. Choose accessories of lightweight, breathable material that wicks away perspiration and does not chafe during prolonged use.

Our advice: Start with a compact running belt for your daily training sessions and expand as your distances increase. For triathlon training a waterproof phone case is an indispensable addition that protects your smartphone during the swimming section or in rainy cycling and running sections.

Frequently asked questions about running accessories

What is the difference between a running belt and a hydration belt?

A running belt is primarily designed for taking your phone, keys, bank card and small essentials. A hydration belt is specifically designed for hydration with bottles or soft flasks and also has the necessary holders for them. Some models combine both functions. For training sessions where hydration is the priority choose a hydration belt. For training sessions where storage space is the priority choose a running belt.

Is a waterproof phone case also suitable for swimming?

That depends on the model. Standard splash-proof cases are not suitable for underwater use. The BTTLNS Endymion 1.0 is specifically designed as a floating waterproof case for use in open water and triathlon. Always check the waterproofing specifications of the specific model before using it when swimming.

How do I prevent my hip bag from bouncing during running?

Choose a hip bag or running belt of stretch material that fits snugly around your hips. Set the size correctly so the bag cannot shift but also does not pinch. A too-loose bag always bounces, regardless of the model. Always test the fit during a short training session before taking it to a race or long endurance run.

Which water bottle fits in a running belt?

Most compact running belts are designed for water bottles of 150ml to 500ml. More extensive hip bags have larger compartments that can hold water bottles up to 750ml. Always check the specifications of your running belt before purchasing a water bottle. Soft flasks take up less space as they empty and are therefore more comfortable than hard water bottles during longer training sessions.

Can I also use a running belt for triathlon?

Yes. A running belt is useful for the running section of a triathlon for taking gels and essentials. For the swimming section you preferably use a waterproof phone case or leave your phone with your bike. Check whether the running belt can be put on quickly in the transition zone before choosing it for race use.
