The Gear: What a T1D Runner Actually Needs to Carry (Part 7 of 12)

 The Gear: What a T1D Runner Actually Needs to Carry (Part 7 of 12)

By Ali | AliRunsOnInsulin.com | The Run Starts Before the Run Series

Let’s talk about what’s actually on my body every time I run.

Because running with T1D isn’t just about managing blood sugar in your head — it’s about having the right things physically on you, in the right places, accessible without breaking stride. The gear you choose either makes this easier or it becomes another variable working against you.

This is Part 7 of 12 in my series on running with Type 1 diabetes. No fluff, no filler — just the actual gear categories, what matters in each, and why.

The Non-Negotiables: What Goes On Your Body Every Single Run

These aren’t optional. Short run, long run, race day, easy recovery shuffle around the block — these come with you every time.

1. Fast-Acting Glucose — Accessible Without Stopping

This is your most important piece of gear and it has one requirement that overrides everything else: it has to be reachable without breaking stride.

Not in the bottom of a bag. Not in a pocket you have to dig for. On your body, in a pocket you can reach with one hand while running.

What you carry is personal preference. Glucose tablets are shelf-stable, portable, and let you dose precisely — four tablets equals 15 grams of fast carbs, no guessing. Gels are faster to consume mid-run and easier to get down when your heart rate is high. Many T1D runners carry both: tabs for early management, a gel for true emergency situations. 

Personally, I like to carry Gen U Can for long slow absorbing carbs, SiS gels for a quick liquid option that doesn’t need water as there are electrolytes and Clif Shot Bloks as you can take one at a time to micro carb if you want. 

The rule: always carry more than you think you’ll need. I have never finished a run wishing I’d brought fewer carbs.

2. Your CGM — Secured

Your CGM is your real-time window into what’s happening. But sweat, heat, friction from clothing, and the natural wear of physical activity can all compromise the adhesive especially on longer runs.

CGM Skin Grip are not optional gear for runners. They’re maintenance. Apply them before runs over 30 minutes as standard practice. Look for waterproof, sweatproof options specifically designed for your sensor model.

A CGM that peels mid-run isn’t just an inconvenience — it’s a safety issue. Secure it.

3. Your Phone — Charged

Your CGM transmits to your phone. Your emergency contacts are on your phone. Your GPS is on your phone. A dead phone mid-run means no CGM alerts, no ability to call for help, and no record of where you are.

Charge it before every run. Not “it has 34% left, that’s probably fine.” Charged.

4. Medical ID

Every run. No exceptions.

If something happens out there a severe low, a fall, an accident first responders need to know you have T1D. They need to know before they make treatment decisions that could make things worse.

Road ID makes athlete-specific ID tags that attach to your wrist, shoe, or watch band. They’re lightweight, designed to survive sweat and weather, and can include your condition, emergency contact, and any critical medical information. This is a one-time purchase that you wear for years.

There is no run short enough to skip the medical ID.

The Carry System: Where Everything Lives

Having the right supplies means nothing if you can’t access them efficiently. The carry system is what makes the difference between a runner who manages well on the go and one who has to stop, dig around, and hope.

The Running Belt

For most T1D runners, a purpose-built running belt is the foundation of the carry system. The key features to look for:

A reinforced pass-through port for insulin pump tubing. An expandable pocket that fits your pump or CGM receiver, glucose tabs, phone, and ID without bulging. No-bounce construction — because a belt that shifts and bounces is one you’ll eventually leave behind. Personally, I have been running with the flip belt for years. No chafe, no bounce and fits everything I need.

For shorter runs where you’re not carrying a pump or much gear, a standard slim running belt works. For anything over an hour, go with a belt that can hold your full kit.

The Hydration Vest

For long runs anything over 90 minutes a hydration vest changes the game. Not just for water, but for storage.

A vest with front pockets gives you instant, no-look access to gels and carbs. A rear pocket holds extra supplies, your phone, or a light layer. The best vests distribute weight across your torso so nothing bounces and nothing shifts. 

For T1D runners specifically, the vest solves a problem the belt doesn’t: you can carry enough carbs for a 3-hour run without stuffing them into a pocket the size of your hand.

The Short-Run Solution

For easy runs under 45 minutes where you’re not carrying full kit, flip belt shorts running shorts with all the pockets are a game changer. . A gel tucked into a waistband pocket is not accessible under pressure. Look for activewear designed with secure, zippered pockets if you’re going minimal.

The Device Layer: Your Tech Stack

CGM

The single most important piece of T1D running technology. Real-time blood sugar data, trend arrows, and alerts that give you the lead time to respond to a dropping number before it becomes a crisis.

Current top options as of 2026: Dexcom G7 and Libre 3. Both are approved for wear during exercise, both transmit to smartphone apps, and both have customizable alert thresholds you should absolutely set before every run. Know which one you’re using and know its lag characteristics — we covered this in Part 3.

Insulin Pump

If you’re on a pump, your device needs to be secured during the run in a way that protects the infusion site and keeps tubing from snagging. A dedicated pump belt or vest pocket designed with a pass-through hole is the right solution — not a clip-on case bouncing against your hip.

For pumps with exercise or activity mode, set it 90 minutes before your run (Part 1 has the full protocol). Know whether your pump’s automated insulin delivery system needs to be adjusted for exercise or switched to a different mode.

Smartwatch / GPS Watch

Not strictly T1D gear, but a smartwatch that displays your CGM data on your wrist changes how you run. Instead of reaching for your phone to check your number, you glance at your wrist. At race pace, that difference in friction is meaningful.

Garmin Forerunner 965, Garmin Forerunner 265, or Garmin Fenix 8 These are the watches I would look at first as they integrate with Dexcom.

The Emergency Layer: What You Hope You Never Use

Identification Card

In addition to your Road ID, a small laminated card in your running belt with your name, emergency contact, CGM type, insulin pump type, and your protocol for treating a low gives first responders everything they need if they can’t reach anyone and you can’t communicate.

One card. Laminated. In your belt. Never leave it out.

The Gear That Makes Everything Work Together

The difference between T1D running gear that works and gear that gets left at home is fit, weight, and accessibility. If it bounces, you’ll ditch it. If it’s too heavy, you’ll leave it on short runs. If you can’t reach what you need mid-stride, it might as well not be there.

Test your carry system on training runs, not on race day. Know exactly where everything lives, how fast you can access it, and whether it stays in place at pace. Adjust before a race, not during.

Your gear isn’t just equipment. For T1D runners, it’s infrastructure. Build it deliberately.
