    Expert Review

    One of my favorite gels for long runs and races. The Maurten Gel 100 has a unique texture that doesn't bother my stomach, even deep into an ultra when everything else starts sounding terrible. My preferred method is to take it down like an oyster—no chewing, just a quick swallow followed by some water. Simple, fast, and easy. The hydrogel technology seems to sit well in my stomach, allowing me to keep taking in carbohydrates without feeling overly sweet or causing GI issues. When you're trying to fuel for hours on end, finding a gel your stomach tolerates is worth its weight in gold, and this one has earned a permanent spot in my race kit.
