Trail race bib holder: belt or magnets—which should you choose?

We’ve all had a race bib bouncing around or coming loose in the first mile. Waist belt or magnets on your clothing: the right trail running race bib holder depends on your budget and where you want to wear your number. In this article, we compare the two types of fastening, review the models on the market, and show you how to adjust your system properly before the race.

Which one to choose based on your fastening method and budget

Your budget and where you want to attach the race bib will determine which of the two types is right for you. If you want to wear it around your waist, see how to choose the right trail running belt before you buy. If you want to avoid pins, magnets are made for that: they keep you from piercing your clothing and attach in seconds. Try the fastening system with your running outfit before the race, never on race day.

For the final price, check the total shown before you confirm, not just the starting price. No pins in your shirt: choose magnets.

Oxsitis magnetic race bib holders: the most affordable option for magnets

The Oxsitis “Magnets sets” kit includes four fastening magnets. It’s the cheapest option on the list: €5.95 for just 10 g, practically nothing in your pocket or on your shirt. The four magnets hold your race bib on your clothing without piercing it with a pin, and they also attach to a pack’s waist strap. For a lightweight bottle belt to pair with your gear, take a look at Kinetik trail running hydration belts Kinetik. Don’t put the magnets in the washing machine: rinse them by hand with clean water, then leave them to air-dry. On a tight budget? This is the smartest choice.

KIPRUN Race Bib Belt: an entry-level belt for beginners

You know the sound of a race bib flapping in the wind on a damp trail at dawn. The KIPRUN belt costs €6.99, adjusts to fit and secures the race bib at three points. For your first trail race, it's a small expense, and it's better to skip the safety pins. The belt can also carry your gels, which means you don't need another pocket on your back. Tighten the strap just enough: the race bib should stay flat and readable at the front, even when you speed up on the descent. To find out what to bring on a course, see the required trail running gear list. For your first race, don't spend more: this one is more than enough.

BV SPORT Race Bib Belt V2: a belt with three attachments and gel holders

The BV SPORT V2 has three attachments to hold your race bib and six pockets for carrying gels without stopping. The listed price is €9.10, making it a good way to try this type of belt before spending more. Six pockets to carry your gels and keep them within reach without stopping is a real advantage over long distances. Adjust the strap before you run and check that your number stays visible at the front. For a long run with water, see how to choose the volume of your hydration pack. It's better to adjust the strap at home than at the start.

Shapeheart Magnetic Race Bib Holders x4: attach your race bib without pins or holes

Each attachment consists of two parts: one on the race bib, the other on the opposite side of the fabric, directly across from it. They connect through the fabric. The magnets hold up to 6 kg, enough to keep the fabric pressed flat against you in the wind. A safety pin coming loose halfway up a climb is annoying: with this system, it takes just a few seconds at the start, and then you can forget about it. Test the attachment on the outfit you plan to race in before the start: put on the exact shirt, take a few strides and shrug your shoulders. A slipping magnet is hard to notice, and it often falls off too late. For a race bib that stays completely still, Kinetik trail running hydration belts Kinetik also offer a reliable alternative. Never trust an attachment you haven't tested while running.

Compressport Race Belt: the adjustable belt with three attachment points

The Compressport Race Belt costs €13, a modest price for an accessory you forget about once you hit the trail. It has three attachment points for securing your race bib and adjusts to your body shape: tighten it around your waist before the start. Wear the belt at the front, with the bib flat against your stomach, and adjust it so it holds the bib without restricting your running. Try a few strides, an uphill stretch, and a downhill stretch. If the strap restricts your breathing or the bib bounces, loosen it by one notch. Don’t set off without testing it.

BV SPORT Magnetic Race Bib Holder: four magnets, one size, sold direct

The BV SPORT race bib holder attaches with magnets. At the start of a race, you still see runners struggling with a safety pin on a too-thin T-shirt. With magnets, it takes just a few seconds. For pricing, go directly to the BV SPORT website: buying from the brand cuts out the middleman. Your number must remain visible on the front from the start to the finish—we’ve all seen a bib folded under a jacket at the first aid station. Belts are allowed in competitions, as long as the number remains visible at checkpoints. Read your race regulations before signing up, and try the system before race day.

Whether you choose a belt or magnets depends on where you want to wear your bib and your budget. Choose the type, try the fastener with your running outfit (a few strides and a downhill section are enough), then check your cart total before placing your order. To complete your running gear, check out the trail accessories Kinetik, designed to keep things simple without adding unnecessary weight.
