You signed up for your first 5K or half marathon, and now it's real. You already run in your shoes, so this kit is the race-day layer on top.

Energy gels keep you fueled on longer runs, and there's a gel for every stomach, from liquid GU to six-ingredient Maurten. A race belt holds your gels and phone, and the bungee toggles hold your bib, so no more safety pins through your shirt. Electrolytes are nice on long, sweaty training runs, and sunglasses make a sunny start line a lot nicer. The gels come from Garage Gym Reviews and NBC Select, the belts from iRunFar, and the electrolytes and shades from Treeline Review and NBC Select. Each card shows the drawback its outlet called out.

Who this is not for. Skip this if you haven't started running yet; the Running Starter Kit covers shoes, socks, anti-chafe balm and a watch first.

Questions people ask

What do you need for your first half marathon?

Your usual running shoes, then energy gels and a race belt to carry them. Electrolytes and sunglasses are nice to have. If you still need the basics like shoes, socks and anti-chafe balm, start with our Running Starter Kit.

What's the easiest energy gel for beginners?

Garage Gym Reviews calls the GU Energy Labs Liquid Energy Gels a good starter gel because the liquid is easier to get down mid-run, though it only comes in a box of 12.

How do you attach a race bib without pins?

Use a running belt with bib toggles or loops. iRunFar's best budget running belt, the UltrAspire Fitted Race Belt 2.0, has two bungee toggles for your bib, though it can bunch up if the pockets are nearly empty.
