Best Triathlon Accessories Under 50 Pounds

You don’t need to spend hundreds of pounds to improve your triathlon performance and experience. These three accessories each cost less than £50 but deliver outsized value, solving common problems that plague triathletes at every level.

What Makes a Great Triathlon Accessory?

The best accessories share common traits: they solve a specific problem, work reliably under race conditions, and require minimal fuss. Whether you’re racing your first sprint triathlon or chasing a Kona slot, these tools make your day smoother and your transitions faster.

Best Overall: TRIWONDER Race Number Belt with Gel Loops

The TRIWONDER Race Number Belt eliminates the frustration of safety-pinning your race number to your tri suit whilst providing convenient storage for nutrition. This elastic belt features integrated gel loops that securely hold energy gels without bouncing or sliding during the run.

What sets this belt apart is its versatility and reliability. The clasp mechanism is easy to operate even with tired, fumbling hands in T2, yet it stays firmly closed throughout your run. The belt sits comfortably on your hips without riding up or causing chafing.

During the bike leg, wear the belt with your number on your back. In T2, simply spin it round so your number faces forward for the run—a two-second transition that saves time and hassle. The gel loops typically hold four to six gels depending on size, providing ample nutrition storage for everything from sprint to half Ironman distance.

At under £15, this is perhaps the best value accessory you can buy. Once you race with a number belt, you’ll never go back to safety pins.

Best Value: Lock Laces Elastic No-Tie Laces

Lock Laces transform your running shoes into slip-ons, eliminating the need to tie knots during transitions. These elastic laces feature a locking mechanism that maintains even tension across your foot whilst allowing easy one-pull tightening.

The installation takes about five minutes per shoe. Thread the elastic laces through your shoes exactly as you would normal laces, adjust to your preferred tension, and lock them in place with the included clip. The excess lace then tucks neatly into the included pocket that sits at the top of your tongue.

What makes Lock Laces particularly effective is the elasticity. Unlike standard laces that can feel too tight or too loose depending on foot swelling during a race, the elastic adapts to your foot’s changing shape whilst maintaining secure fit. This matters especially on longer races when your feet swell.

The time saving in transition is obvious—simply slip your feet in and go. But the real benefit extends beyond saved seconds. With Lock Laces, you never have to waste mental energy wondering if your laces are properly tied or worry about them coming undone mid-race.

Available in numerous colours to match your shoes, Lock Laces cost around £8 and will last for years.

Best Premium: Zone3 Swim Safety Buoy/Tow Float

The Zone3 Swim Safety Buoy is non-negotiable equipment for open water swimming training. This brightly coloured inflatable float trails behind you via a waist belt, making you visible to boats and kayakers whilst providing flotation if you need to rest.

What elevates the Zone3 model above basic alternatives is the dual-chamber design and integrated dry bag compartment. The dual chambers mean that even if one develops a leak, you still have flotation. The dry bag securely holds your keys, phone, and even a small snack—practical features that matter when you’re parking your car and heading straight to the water.

The waist belt adjusts easily and sits comfortably without riding up or chafing. Crucially, the float trails far enough behind that it doesn’t interfere with your stroke or create drag during your swim. You’ll forget it’s there until you need it.

Whilst you won’t use a tow float on race day (they’re training tools, not racing equipment), this accessory is essential for safe open water training sessions. At around £30-35, it’s a small price for significantly improved safety and peace of mind.

Buying Tips: Getting the Most from Your Budget

Quality Over Quantity: Rather than buying multiple cheap accessories that break or underperform, invest in fewer items that work reliably. All three products featured here have proven track records and positive long-term durability.

Test Before Race Day: Purchase these accessories well before your target race. Use them in training to ensure proper fit and function. A race belt that doesn’t stay put or laces adjusted too tight will cause problems best discovered in training, not during your race.

Consider Multiples: Lock Laces are inexpensive enough that you might want sets for multiple pairs of shoes—your racing flats and your training shoes, for example. Similarly, having a backup race belt ensures you’re never caught out if one breaks.

What These Accessories Solve

Each of these accessories addresses a specific pain point. Race belts eliminate pinning-related frustration and provide nutrition storage. Elastic laces save transition time and remove the possibility of untied shoes. Tow floats make open water training safer and less anxious.

Together, they represent less than £60 in total investment but will serve you for years across dozens of races and hundreds of training sessions. That’s the definition of good value in triathlon equipment—solving real problems with reliable solutions at reasonable prices.
