HYROX Anaheim 2026: race-morning sodium + creatine
For HYROX Anaheim, December 3–6, 2026, DO IT's race-morning advice is to arrive hydrated, eat your usual salted food or a familiar sodium drink, and keep creatine at your normal daily dose with no race-week loading. There is no single sodium dose that fits every athlete. Your sweat losses, race duration and normal diet matter more than the city on your race ticket.[1–3]
This guide covers fluid, sodium and creatine, not a complete carbohydrate-fuelling plan. DO IT sells a creatine-electrolyte powder; you do not need it to follow this guide.
Anaheim details: plan around your wave, not the event opening
The official Centr HYROX Anaheim page lists December 3–6, 2026 and says individual start times will be linked approximately three days before the event. The provisional schedule is for planning; check your assigned start time before setting meal and drink reminders.[1]
Battle Bunker's event guide lists the Anaheim Convention Center as the venue.[4] Confirm venue and arrival instructions in the organizer's final athlete information. We have not verified an indoor temperature forecast or the race-day water-station layout. Do not use a December outdoor forecast to assume you will sweat less inside. Follow the event's athlete information for access to fluids.
Your race-morning fluid and sodium timeline
Use this relative to your own start, including an afternoon or evening wave. These are general adult exercise guidelines from the ACSM's 2007 fluid-replacement position stand, not a HYROX-specific dosing trial.[2]
| Time before your start | Practical plan | Example for a 75 kg athlete |
|---|---|---|
| At least 4 hours | If prehydration is needed, slowly drink about 5–7 mL/kg. Include familiar sodium-containing food or a drink with your normal meal. | 375–525 mL, not a large last-minute chug. |
| About 2 hours | If you have not passed urine, or it is dark/highly concentrated, the ACSM suggests another 3–5 mL/kg slowly. This is conditional, not an automatic second bottle. | An additional 225–375 mL only if needed. |
| Final hour | Stick to the routine you have tolerated in training. Do not force extra fluid to meet a bottle target. | Keep a familiar drink available; no catch-up litre. |
| During the race | Use your rehearsed fluid plan and the available drinking opportunities. Avoid drinking beyond your losses. | Needs differ; the pre-race quantities above are not hourly race targets. |
| After finishing | Replace fluid and electrolytes through normal food and drinks; individualize if recovery time is short. | A meal and drinks, rather than repeating pre-race doses by default. |

The ACSM notes that sodium-containing drinks or salted snacks/meals can help retain pre-exercise fluid. That does not mean everyone needs a salt tablet or a 1,000 mg sodium supplement before the start.[2]
How much sodium should you take before Anaheim?
There is no verified Anaheim-specific milligram requirement. Start with a familiar meal and fluid routine. If you have measured high sweat losses, use those results to plan with a sports dietitian rather than adopting another athlete's dose. Sodium from breakfast, electrolyte drinks, gels and tablets all counts.
Sweat rate and sweat sodium concentration vary between people. A sweat-loss estimate is not an instruction to replace every milligram during the race.[2] Our HYROX sodium guide explains the calculation. If you estimate sweat rate from body weight, account for drinks consumed, urine passed and session duration; a one-hour example does not apply unchanged to a 90-minute session.
Do not try to “bank” hydration by drinking as much as possible. Overdrinking can dilute blood sodium, and adding electrolytes does not make excessive fluid intake safe.[2]
Creatine: keep the daily habit, skip the race-week catch-up
The Australian Institute of Sport describes 3–5 g of creatine monohydrate daily without loading as a way to raise muscle creatine gradually, reaching saturation over about four weeks. Loading is an alternative, not a requirement.[3]
- Already taking creatine consistently? Keep your established, tolerated routine. There is no reason in this guide to add an extra race-morning dose.
- Not taking it yet? A first scoop on race morning is not the same as several weeks of use. Do not expect immediate saturation or a guaranteed faster HYROX time.
- Considering loading during race week? It is unnecessary for this plan. The AIS notes possible body-mass gain and gastrointestinal upset, and recommends experimenting with supplements in the off-season.[3]
Creatine and sodium serve different purposes. Your daily creatine dose is not a measure of your race-day sodium or fluid needs.
Where DO IT fits, and where it does not
According to the DO IT product facts, one scoop contains 5 g creatine monohydrate, 1,000 mg sodium, 200 mg potassium and 60 mg magnesium, with no caffeine. The label directs one scoop once daily and no loading phase.[5]
That is a product composition, not a recommended sodium dose for every Anaheim athlete. If it is already part of your routine, count its sodium alongside food and other drinks. Do not use extra scoops to creatine-load or to chase sweat replacement. A separate creatine product and familiar food or electrolyte drink let you adjust those choices independently. Follow product directions and do not exceed the recommended dose.
If you have been told to restrict sodium, or have kidney, heart or blood-pressure concerns, ask your clinician for an individual plan rather than following these general quantities.

FAQ
When is HYROX Anaheim 2026?
The official Centr HYROX Anaheim event page lists December 3–6, 2026. Check the organizer's athlete information for your individual start time.[1]
How much sodium do I need on HYROX Anaheim race morning?
There is no single Anaheim-specific dose. A familiar salted meal or sodium-containing drink can support pre-race hydration; account for all sources and individual sweat losses rather than automatically adding 1,000 mg.[2]
How much should I drink before my start?
The ACSM gives a starting example of 5–7 mL/kg at least four hours before exercise when prehydration is needed. Another 3–5 mL/kg about two hours before is conditional on no urine or dark/highly concentrated urine, not a compulsory extra drink.[2]
Should I load creatine during HYROX race week?
You do not need to load. The AIS describes a no-loading approach of 3–5 g daily that increases muscle creatine gradually over about four weeks. Race morning is not the time to test a new supplement routine.[3]
Do I need DO IT Creatine Hydration to follow this plan?
No. Familiar food and drinks can supply sodium, and creatine can be taken separately. DO IT combines 5 g creatine and 1,000 mg sodium per scoop; that does not make one scoop the right sodium dose for everyone.[5]
