ATHX Race demands sustained energy across three major pathways for 2.5 hours of continuous exertion. Carbohydrates are your primary fuel source, with pre-session intake helping ensure adequate energy availability. Consuming 40-60g of fast-acting carbs 30-90 minutes before training can support your workout readiness. For this reason, we've included Impact Pre-Workout, Origin Pre-Workout Alpha, and THE Pre-Workout as these convenient pre-session formats are designed to be consumed before training.

For an ATHX Race, we recommend Origin Intra-Workout and THE Electrofuel. These formats can be pre-mixed into shakes for easy consumption during activity without interrupting your rhythm. The 2.5-hour duration requires consistent fueling to prevent energy depletion before the final MetCon X zone, hence the inclusion of carbohydrate-electrolyte solutions which contribute to the maintenance of endurance performance during prolonged endurance exercise¹.

The combination of heavy compound lifting and high-intensity functional movements causes significant muscle protein breakdown. Protein contributes to the maintenance of muscle mass², making post-session nutrition an important recovery component. We've selected All-in-One Recovery, Impact Soy Protein, and THE Recovery as products specifically formulated for recovery during the optimal 30-120 minute post-session window.

For an ATHX Race, begin fueling during the first recovery window (the 10-minute Refuel Zone after the Strength Zone). Do not wait until you feel depleted. Early intake prevents glycogen depletion and maintains blood sugar stability. Aim for 30-60g carbs per hour, adjusting based on pace and conditions. Portable, pre-mix formats like Origin Intra-Workout allow easy consumption without breaking stride.

Muscle cramping during ATHX Race often stems from heavy sweat losses combined with inadequate sodium and fluid replacement. There are a few handy solutions to conquer cramps:

• Pre-hydrate with 500-700mg sodium before the event

• Consume 500-700mg sodium per hour during the event

• Maintain fluid intake of 400-800ml per hour

• Practice your fueling strategy during training

Race-day nutrition is only part of the bigger picture. How you fuel before and after ATHX Race makes a huge difference to your training and recovery.
