6AM Run Marathon Pre-Workout Review

Generic pre-workouts often leave me feeling jittery and bloated on a run, so I was curious about 6AM Run's Marathon — a pre-workout formulated specifically for running stamina rather than gym lifting.

Taste and Mixing

I tried the raspberry flavor, which mixed cleanly with no gritty texture and a pleasant, not-too-sweet taste. It dissolved fully in cold water within a few stirs.

On the Run

I used it before several training runs ranging from 4 to 10 miles. Energy felt steady rather than a hard spike-and-crash, and importantly, I didn't experience the stomach discomfort I sometimes get from lifting-focused pre-workouts during a run.

Pros

Pros: running-specific formula with steady energy, no GI discomfort during runs in my testing, pleasant flavor that mixes cleanly.

Cons

Cons: at $59.99 it's pricier than generic pre-workouts, and if you're not a runner, a standard pre-workout may serve you just as well.

Final Verdict

For dedicated runners who've been frustrated by lifting-focused pre-workouts upsetting their stomach mid-run, 6AM Run's Marathon is a genuinely purpose-built alternative.

Currently $59.99 on the 6AM Run site. See the current price here.
