Mountain Fuel Xtreme Energy Tropical Energy Powder

Mountain Fuel Mountain Fuel Xtreme Energy Tropical Energy Powder is a drink mix with 39.8 g of carbohydrate, 102 mg of sodium and no caffeine per serving. It scores 68/100 on the CarbRate Science Score. At 60 g of carbs per hour that is one and a half servings an hour.

Who Mountain Fuel Xtreme Energy Tropical Energy Powder suits

Runners fueling below about 60 g per hour. Without a fructose source, absorption tops out near 60 g/hr, so stacking servings past that point tends to cause gut trouble rather than more energy.

Runners who want fewer servings to carry. At 39.8 g per serving, an hour at 90 g/hr is 2.5 servings, which matters over a marathon or ultra where pocket space and hand-offs are real limits.

Runners who want to keep caffeine separate, or race caffeine-free. Caffeine-free fuel is easier to repeat every 20 to 30 minutes without stacking a stimulant.

Long steady efforts more than hard racing. Protein slows gastric emptying, and this one carries 5.1 g per serving.

Runners with dietary limits: it is vegan according to the manufacturer.

How to use it in a race

Start early. Take the first serving 15 to 20 minutes into the race, before you feel you need it, and repeat on a fixed clock. At 60 g/hr that is one and a half servings per hour; at 90 g/hr it is 2.5.

Drink texture, so it goes down without much water. Still sip at aid stations; carbohydrate absorbs faster when the stomach has fluid to work with.

Practice it on long runs at race intensity before you race on it. Gut tolerance is trained; a fuel that felt fine at easy pace can behave differently at marathon effort.

Cost at 60 g/hr works out to about $3.54 per hour at list price, or roughly $12 for a three-and-a-half hour marathon.

Servings per hour assume the 39.8 g per serving on the label. The finder sets your own g/hr target from race distance, sweat and gut.

Why it scores what it does
