Xact Endurance Bar (Single Serving)
Real fruit, dates, and almonds deliver the sustained energy your longest efforts demand. Soft, compact, and built for distance, this is fuel that actually satisfies.
The Bar for Your Biggest Days
We love carbs. But somewhere around hour three of a day out, you realize: you need more than just energy. You need substance.
XACT Endurance Bars are built for exactly this; the long rides, the big climbs, and those days when you're out there for hours and your fuel needs to keep up with your ambition.
Made from almonds, dates, and dried fruit, these bars deliver 16g carbs, 5g protein, and 6g healthy fat. That balanced mix means steady, satisfying energy that keeps you fueled for hours. Your hunger quiets. You keep going.
Real food. Real satisfaction. Soft. Ready. Reliable.
Why They Made This:
At Xact, they know fuelling isn't one-size-fits-all. After thousands of conversations with athletes, they kept hearing the same thing: sometimes you want a break from super sweet fruit bars. Sometimes you want something more substantial.
Taste and texture matter as much as nutrition. There's no point building endurance sport fuel if you can't chew it while breathing hard, or if you dread eating it mid-effort.
So they built the Endurance Bar to be the perfect pairing to their Fruit Bars.
It's not the only slow-release bar out there. But it's the one that remembers you're a human, not just an engine. High-quality ingredients wrapped up in a soft, easy-to-chew format that works whether you're cruising steady or pushing harder than you planned.
Going on a long-outing? Well now you can pair Endurance Bars with Fruit Bars and you've got options. Need sustained hunger control during the steady climb? Endurance Bar. Hit a hard section and need quick energy? Fruit Bar. Want variety when palate fatigue sets in? You've got both.
This is the fuel system built around how athletes actually fuel—mixing formats, matching effort, staying fuelled without getting bored.
How do Endurance Bars deliver sustained energy?
It's all about the macronutrient combination. Soluble fiber slows glucose absorption, preventing the blood sugar spikes and crashes you get from pure carbs. The almonds delay gastric emptying, which means your body releases energy gradually over hours instead of burning through it in minutes.
In short: fiber + fat + protein = slows energy supply.
Should I always choose slow-burning carbs?
Not necessarily. It depends on your effort intensity:
- Steady, long-duration efforts (Zone 2, ultra-endurance): Slow-burning carbs help maintain stable energy and control hunger.
- High-intensity efforts (racing, hard surges): Fast-burning carbs (like our Fruit Bars and Gels) provide the immediate fuel your muscles demand.
The optimal strategy: Pair slow carbs (Endurance Bars) with fast carbs (Fruit Bars or Gels) to match your effort's demands. Low intensity? Lean on Endurance Bars. Hard efforts? Mix in faster carbs. This is why the XACT Fuelling System works — every product has a role.
How to Use:
For low-intensity, long-duration efforts (hiking, steady rides, long runs): 1–2 Endurance Bars per hour, depending on duration and hunger.
For high-intensity efforts or races: Start with an Endurance Bar for sustained energy, then switch to Fruit Bars or Gels when intensity rises and you need faster carbs.
Pro tip: One bar per hour works well for moderate efforts; stack with other XACT products to hit your carbohydrate targets (30–90g/hour depending on session length and intensity).
