MarchMix is the first hydration mix created specifically for the marching arts. Built for performers spending hours rehearsing in the heat, it supports hydration through long blocks, full ensemble runs, and one more rep that turns into five.

Getting band members hydrated is at the heart of MarchMix. When you’re marching, playing, and searching for a dot that even the artistic director can’t find, your body has plenty to handle.

And performers are feeling a difference. Their feedback tells us what they notice on the field. The science helps explain why replacing the fluid and sodium lost through sweat matters during those demanding rehearsal days.

At the time of writing, 48 participants rated the effects of MarchMix an average of 4.06 out of 5. They reported steadier energy, less exhaustion, better focus during rehearsal, and easier recovery.

“I feel way more steady energy throughout the rehearsal day and never feel the need for more hydration than I'm taking in”

Salvador Sanchez, Low Brass

Steady energy means something when you still have hours of rehearsal ahead. So does feeling comfortable enough to drink during a block and get moving again.

“My body absorbs the march mix incredibly quickly. This makes running back on resets not make my stomach slosh around”

Cody Brown, High Brass

These are the moments MarchMix was built around. The research behind hydration gives us a way to understand why replacing sweat losses could help performers feel better throughout the day.

Sweating helps cool your body. It also carries away water and sodium.

Those losses vary between people. In a study involving more than 500 athletes, researchers found substantial differences in sweat rate and sweat sodium concentration. Performers sharing the same field and rehearsal schedule can have different hydration needs. Baker et al., 2016

Over a long rehearsal, those losses add up. Replacing fluid and sodium becomes part of keeping your body ready for the work ahead.

During rehearsal, your cardiovascular system delivers blood to working muscles and supports blood flow to the skin to help release heat. Dehydration can increase the strain of doing both.

Researchers studied eight trained cyclists exercising for two hours in warm conditions while drinking different amounts of fluid. Greater dehydration was associated with higher heart rates, higher core temperatures, and less blood pumped with each heartbeat. Replacing more of their sweat losses reduced those changes. Montain and Coyle, 1992

That research helps explain why hydration matters when exercise and heat overlap. Performers describe their side of the story through the way a block feels:

“After drinking I felt like the heat wasn’t getting to me as badly, and that it was much easier to stay focused throughout the blocks that I used it”

The science measures the extra work dehydration puts on the body. The performer describes feeling more able to handle rehearsal. That connection is one reason the pilot feedback is encouraging.

Drinking fluid is part of hydration. Retaining that fluid matters, too.

In a controlled study, six men drank beverages with different sodium concentrations after becoming dehydrated through exercise. Drinks containing more sodium helped them retain a greater fraction of the fluid they consumed during recovery. Maughan and Leiper, 1995

This finding supports sodium’s role in rehydration after sweaty exercise. The amount someone needs depends on their losses, how much they drink, and what they eat. More sodium doesn’t automatically mean better hydration.

For performers facing another block after a break, recovery is part of the rehearsal day itself. Replacing what was lost helps prepare the body for what comes next.

Performers aren’t thinking about fluid retention or blood pumped per heartbeat when they’re running back to a reset. They’re thinking about how they feel and whether they’re ready to do it again.

“Since I started using it I’ve noticed I have been less prone to headaches, fatigue, and grogginess during rehearsal”

Atticus Ence, High Brass

Science tells us that limiting dehydration can reduce cardiovascular and thermal strain during exercise in the heat, and that sodium can help retain fluid during recovery. Performers tell us about steadier energy, more comfortable resets, and rehearsal days that feel more manageable. Montain and Coyle, 1992; Maughan and Leiper, 1995

Our pilot captures that experience. Its 4.06 out of 5 average rating from 48 participants is encouraging early feedback, while research supports the hydration principles behind MarchMix. Measuring exactly how much MarchMix changes hydration or performance is the next step.

MarchMix was created for the demands of the marching arts. Hearing performers say they feel more ready for the next block gives us a reason to keep building it.
