Nutrition during the Iron Viking

Running an Iron Viking means burning thousands of calories and losing liters of fluids. Nutrition and hydration are therefore crucial! Along the course, you’ll find water stations and aid stations offering things like energy gels. But as an Ultra or Iron participant, you get an extra advantage: at the start/finish zone, you’re allowed to place your own bag with food and drinks. Make smart use of it!

Proper preparation starts with proper nutrition

Carb up in the days leading up to the run so you can hit the start line fully energized. Use your training to test what your stomach can handle during long efforts, don’t try anything new on race day! Tip: schedule one or more long runs to practice your nutrition strategy. That way, you’ll know exactly what works for you when it matters most.
