Real fueling setups for long rides, runs and race days.

★★★★★
Maintaining energy
"I can go on 4+ hour rides and feel amazing during and after."


★★★★★
Digestion
"Zero gut issues. Simple formula that works."
★★★★★
Value
"Still the best value carbs I've found. Neutral flavor is great."

Use one scoop for 30g of carbohydrates, two for 60g or three for 90g. Match the amount to your workout’s duration and intensity, and increase gradually according to your personal tolerance.
Formula 369 has a light, neutral taste designed to remain easy to drink throughout long workouts. It avoids the heavy sweetness and strong flavors that can become difficult to tolerate over several hours.
No. Formula 369 is caffeine-free, giving you control over whether and when you add caffeine to your fueling strategy.
Formula 369 is a carb drink mix, so your fuel comes from your bottle. Use 30g, 60g or 90g depending on your workout, with sodium included, so 2–3 gels are not needed. When carrying a bottle is not enough, CARB DOPE gives you 45g of portable carbohydrate fuel.
No. The Starter Pack is a one-time purchase with no recurring deliveries or subscription commitment.
That depends on the number of scoops you use per workout. At one scoop per session, the 3 lb bag provides 45 sessions, the 5 lb bag provides 73 and the 10 lb bag provides 146. Using two or three scoops per session will reduce the number of sessions accordingly.
