Hyrox punishes bad kit choices faster than almost any other race format. You're running 8km and grinding through eight stations in the same outfit, with no chance to change, so anything that chafes, shifts or overheats in kilometre one is still a problem at kilometre seven. What holds up:
Footwear: grip over cushion
Race-day trainers need to do two conflicting jobs: run comfortably for 8km and grip confidently through sled pushes, lunges and burpee broad jumps. A pure road-running shoe with soft cushioning will slide during sled work. A rigid training shoe will feel harsh by the fifth kilometre.
Look for a shoe with a firmer, grippier outsole and enough cushioning to survive the running segments. If you already own trainers you've trained the full 8-week block in, race in those. Race day is the wrong time to try something new, no matter how good it looks.
Tops: fitted, breathable, no chafing
A loose, flapping top might feel fine in the gym but becomes a genuine problem during farmers carries and sled pulls, where fabric bunches and rubs. A close, breathable fit is the safer call for race day specifically, even if you train in something baggier day to day.
Moisture-wicking fabric matters more here than in a standard gym session. You'll be sweating heavily for well over an hour, and a top that holds moisture gets heavier and colder as the race goes on.
Bottoms: leggings or fitted shorts, tested beforehand
This is where fit problems show up mid-race. Leggings that slide down during a sandbag lunge or shorts that ride up during a burpee broad jump will cost you time and attention you need elsewhere. Whatever you choose, wear it for at least one full training session that includes sled work before race day. Sled pushes in particular expose a waistband that isn't secure.
Sports bra: support that survives impact, not just running
Burpee broad jumps and running both demand real support, and a bra that's fine for a steady jog can feel very different mid-jump. If you're not sure your current sports bra holds up under that kind of impact, our guide on how a sports bra should fit covers what to check before race day, not after.
Socks and small details
Blisters ruin more races than bad training does. Wear the socks you've trained in, not new ones out of the packet. If you're prone to blisters on longer runs, that risk only increases across 8km plus station work, so tape or treat problem spots before you start, not after you feel them.
What to leave at home
Skip anything with pockets that bounce, jewellery that could catch during carries, and any brand-new item you haven't tested. Race day rewards boring, proven kit choices over exciting new ones.
Building a full race-day kit
If you're kitting out from scratch, our Hyrox collection is built specifically around this brief: fitted, breathable, grip-tested through sled work, and built to hold up across both the running and the stations. It's the same kit we'd point you to for the training block itself, not just race day, because what works in week 6 of your 8-week plan is exactly what should carry you across the finish line.
Whatever you choose, the rule holds: nothing new on race day. Train in it, trust it, then race in it.
