Trail Running vs Ski Mountaineering: How Vanessa Chavarriaga Posada Fuels Both

From breaking trail in the alpine to flowing through long trail miles, Vanessa Chavarriaga Posada approaches every adventure with intention. In this conversation, she shares how her fueling strategy shifts between ski mountaineering and trail running, why winter hydration matters more than most athletes realize, and how her work in environmental sociology shapes the way she shows up in the outdoors. It’s about staying sharp, staying fueled, and making space for more people to belong outside.

Does your use of Tailwind's product change whether you are ski mountaineering vs. trail running? If so, what changes?

Slow is fast when it comes to ski mountaineering. Breaking trail, bootpacking, or navigating with crampons and ice axes are crucial moments for concentration and risk assessment. I stay sharp and focused with a constant input of Endurance Fuel. In comparison, trail running is all about being fast and flowy. My heart rate is usually higher and I am trying to keep up on my carbs every hour. High Carb Fuel works great for the 20+ mile runs. I also love digging into the Caffeinated Endurance Fuel on long days, regardless of the activity!

Not a lot of people think they need to drink/eat while skiing (especially at a resort) because it's cold out. What advice might you give them for why it's important?

Fueling in the winter is tricky. Who wants to chug water when you can't feel your fingers or toes? However, it's just as important as fueling during the summer months. Even though we may not be visibly sweating, we are still losing moisture through our heavy breathing and exertion on the slopes. We have to keep ingesting calories, electrolytes, and hydration. It's what helps your muscles recover instead of cramp between laps. It also gives you the energy to keep pushing for a full day of skiing, and to beat the post-lunch slump. I keep a soft flask inside my jacket to ensure it doesn't freeze. And on extra cold days, I carry a thermos. Pro tip: add the Naked Endurance Fuel to your favorite tea for a warm alternative!

Can you explain what environmental sociology is and how it relates to your ski and run adventures?

Environmental sociology studies the relationship between people and nature. In my work, I specifically talk about the intersections of racial identity and outdoor access. Outdoor recreation (like skiing and trail running) relies on having access to trails, transportation, clean air, and clean water. In the United States, communities of color have been disproportionately impacted to live in neighborhoods where access to all of these things is virtually nonexistent. This creates a disparity in access, and perpetuates stereotypes that people of color don't belong outside. Taking up space in these sports helps me disrupt these narratives, educate others, and remind people of color that we belong. 

What's your favorite Tailwind product and flavor?

Mandarin Endurance Fuel and Salted Caramel Recovery Mix.

Anything else we should have in mind or tips you'd like to share?

Fuel before you get hungry!! It's much easier to stay out of a calorie deficit than try to recover from one while on the mountain. I try to set a reminder on my watch or phone to fuel every 30 or 60 minutes. This is the key to being able to play outside all day long.

We can all play a role in making the outdoors a welcoming space. Whether it's sharing a skill, a sport, a tradition, or a simple invitation to go outdoors -- we can make a difference.
