Essential Half Marathon Gear Checklist

Getting the right gear dialed in during training means race day is one less thing to think about. This checklist covers what you actually need — for the weeks of training leading up to your race and for race morning itself — organized so you can scan it and check items off.

Training Gear Checklist

Race Day Additions

These go beyond your training gear — pack them alongside your usual kit for race morning.

Running Shoes

Choose a shoe built for the type of running you'll be doing — road, trail, or a mix — and try it on with the socks you'll actually train in. Leave room in the toe box for your toes to splay, but keep the fit snug rather than loose. Do a few jumps or a short jog in the store before buying, then break the shoes in gradually over a few weeks rather than debuting them on a long run. Replace running shoes every 300-400 miles; tracking mileage on a sports watch makes this easy to catch before the cushioning breaks down.

Clothing

Look for synthetic fabrics — polyester and spandex blends — over cotton, since they wick sweat away from your skin instead of holding onto it. Clothing should fit close to the body without being restrictive: too loose and it chafes or bunches, too tight and it limits your range of motion. Layering lets you adapt as your body temperature rises over the course of a run; for exactly how to layer by race-morning temperature, see the half marathon wardrobe guide rather than guessing.

Electronics

A sports watch is the most useful piece of running tech — pair a goal pace from a pace calculator with your watch's lap and pace features so you know exactly how fast to run each mile in training and on race day. A phone with a running app is a fine substitute if you'd rather not buy a dedicated watch. Heart rate monitors are optional but useful if you're training by effort zones rather than pace alone.

Sun Protection

Sunglasses should block 99-100% of UV rays regardless of lens darkness — darker lenses don't automatically mean better UV protection, so check the label. For sunscreen, use a broad-spectrum SPF 30 or higher, apply it about 15 minutes before heading out so it has time to bind to your skin, and reapply every two hours or after heavy sweating on longer runs. Don't skip your ears, neck, and hairline.

Nutrition and Hydration Gear

Energy gels give you an easily digestible, fast source of carbs and electrolytes during long stretches; test brands and flavors during training long runs, not on race day. Electrolyte drinks replace the sodium, potassium, and calcium you lose through sweat — if you're running more than an hour, aim for at least 16 ounces before you start and about 8 ounces every 20 minutes during the run, then dial in the exact amount for your body weight and the day's weather with a hydration calculator. A hydration belt is worth it if you'd rather carry your own fluids than rely on aid stations; see our guide to hydration packs if you're deciding between the two.

Small Extras That Matter

Blister prevention — running-specific socks, lubricant, or blister tape on hot spots — is the cheapest insurance you can carry against a problem that can derail a race. Pack a couple of hand wipes for pre-race portable-toilet trips, and carry ibuprofen or acetaminophen only if you already know it agrees with your stomach; taking a new medication on race morning isn't worth the risk. For more on preventing the overuse issues gear alone can't fix, see our guide to preventing running injuries.

Frequently Asked Questions

What gear do I need for a half marathon?

A complete kit covers training and race day. The core essentials are properly fitted, broken-in running shoes and moisture-wicking clothing, plus a sports watch for pacing. Add sunglasses, headwear, and SPF 30+ sunscreen for sun protection, and nutrition items like energy gels, electrolyte drinks, and protein bars. Round it out with hydration gear and small extras like blister prevention, hand wipes, and pain relievers.

How do I choose the right running shoes for a half marathon?

Choose a shoe designed for the type of running you'll be doing, then try it on with running socks to check the fit. Leave room in the toe box for your toes to splay, but keep the shoe snug rather than loose or constrictive. Do a few jumps or a short run in the store to test comfort, then break the shoes in gradually over a few weeks before race day.

What should I wear for a half marathon?

Wear moisture-wicking clothing that pulls sweat away from your skin and keeps you dry. Synthetic fabrics made of polyester and spandex work well because they're lightweight, breathable, and durable, so avoid cotton. Choose a form-fitting cut that isn't too loose or too tight, and layer for temperature regulation so you can adapt to changing conditions.

What nutrition and hydration gear should I bring on race day?

Pack energy gels for an easily digestible, quick boost of carbs and electrolytes during long stretches, and a protein bar or easy-to-digest snack for after you finish. For fluids, plan around water bottles, a hydration belt, or the course's own aid stations; if you're running more than an hour, aim for at least 16 ounces of electrolyte drink beforehand and about 8 ounces every 20 minutes during the race.
