Marathon, Half Marathon, Ultra Marathon Running Belt

Why do you need a SPIbelt for your half marathon, marathon, or ultra marathon?

When running long races, armbands can only hold your phone, are prone to slip, chafe, collect sweat, and makes one arm heavier than the other. SPIbelt is a more sleek, low-profile way to carry your essential race day items that’s lightweight and doesn’t bounce around. This makes it the ideal belt for marathons, or 5k, or 10k, or half marathons, and especially ultra marathons where runners need to constantly re-fuel. If you’re preparing for a big run, whether you’re a beginner to a seasoned professional runner– we have the fitness belt for you.

Need to carry energy gels?

Our Performance Series SPIbeltEndurance Series SPIbelt, and SPI H2O Venture Series all have a place to hold nutrition to fuel up mid-race. The gel loops on these race fuel belts will hold GUs, Honey Stingers, Clif Shots, or PowerBar Gels safe and snug without taking up space in the pocket.

Need a hydration solution?

For many longer race types, hydration is key to finishing with a good time. Our water bottles slide easily onto the elastic of your race belt so you can stay hydrated with water or your favorite diluted electrolyte or energy drink making the SPI H2O Companion the perfect running partner. The SPI H2O Venture Series takes it one step further with bigger bottles that can be placed anywhere along the elastic – comfort and options are what makes this hydration running belt a standout product.

Need something to hold your race bib?

Sticking safety pins into your expensive running clothes, taping a piece of paper to your leg, and all of the other ways race day runners attach their running numbers to their bodies is downright inefficient.

Used in conjunction with your SPIbelt, we offer Race Toggles that easily attach your race bib to your SPIbelt. No holes in your clothing, no tape, just a simple, cheap, and easy solution.

Need something light-weight and won’t weigh you down?

The Original SPIbelt weighs in at just 3 ounces, making it an extremely light option for runners who can’t be weighed down by bulky items. You’re trying to get the best time possible, you can’t have heavy gear draining all of your energy!

Our goal is to have the simplest and most functional marathon belt out there so you can focus on the important stuff. Plus, it’s always a good idea to run with your ID or driver’s license. So keep your essentials safe and accessible along with anything to boost your race day performance.

SPIbelt Reviews


Original and Large Pocket SPIbelts

“The SPIbelt is fantastic! You get it out of the package and think this is never going to hold my phone. But it does! It is stable around your waist and looks great. Makes getting to your stuff a lot easier than an armband I assure you! I love it!!!” – Missy

“As an amateur bodybuilder, I bought the original SPIbelt after I became frustrated using the armband case to house my iPod during my weight training workouts. What I really love about it most is that it does not constrict my bicep muscles during my arm workouts. In addition, the belt is flexible and really stays put whether running on the treadmill or on any of the elliptical machines. Love my SPIbelt!”  – Stella S

“I love my SPIbelt! It doesn’t bounce around at all. Actually, I can barely even tell I’m wearing it. There is plenty of room for my iPhone 5 in a Commuter Series Otterbox. I’m sure I could still squeeze a few more small things into the SPIbelt as well. The REAL best thing about the SPIbelt is that it doesn’t look like a huge fanny pack! LOL I would recommend a SPIbelt to anyone, even if they aren’t runners. Great job!!!!”  – Becky S


“I purchased an SPIbelt to hold my insulin pump when I run agility with my dog. It stays in place, doesn’t bounce or move and I often forget it’s even there. So happy I purchased it and will probably purchase some other items in the future. Great product!” – Elizabeth

“I just love my SPIbelt. I recently upgraded to an iPhone 6 Plus and it fits perfectly in my large pocket SPIbelt even with a Speck case on it. I don’t even know I am wearing it. I definitely recommend this product to anyone who runs with their phone on them.” – Rob P

“I run 4.5 miles per day and the belt is WAY BETTER than the arm band holders. I was very skeptical about the feel and bounce of the belt. It does not bounce at all and the feel is great. I place the pocket (off midline) for better comfort. It holds my iPhone, keys and ID very well. Great purchase on my part.” – Ed M

“I have the huge Galaxy Note 2 and a bulky case. This SPI Belt fits my phone, an energy bar, and my keys while running with no bounce or trouble. Great product.” – Bryan

Performance Series

“Hands down the best running belt you can purchase. I have owned two, just upgraded to the Performance Series belt and love it. I have run thousands of miles wearing the SPIbelt, I wear it on every run including many many marathons. Fits perfect, you really can not tell if you are wearing it at all and does not bounce even with cell phone inside. You will not be disappointed at all really 5 star product.”  – John P

“This [the Endurance Series] is by far my favorite SPIbelt product. I love the amount of things I can fit in here, especially for my long races. The bib toggles work well and I have been able to fit a gel, two sets of of keys and a cell phone and still forget I was wearing the belt. I recommend this to anyone who is doing long distance, endurance events.”  – Jessica K. “I LOVE THIS. I am training for a marathon and wanted something small to carry my gels and cell phone. This belt is great! Stays in place (no bouncing) and holds EVERYTHING. It is a must for longer runs.” –  Michelle
