Key takeaways

  • Start every trail run well hydrated.
  • Use a hydration vest or soft flasks for longer distances.
  • Drink regularly throughout the route.
  • Take temperature and elevation changes into account.
  • Hydrate after finishing as well.

Who is this relevant for?

For trail runners, ultrarunners, and runners who regularly train off-road or in hilly terrain.

Why are people searching for this?

Due to longer durations, elevation changes, and fewer supply points, trail running often requires more preparation than a regular running workout.

What do you need to know?

  • Drink before you set off.
  • Use a hydration vest or soft flasks.
  • Plan refill points where possible.
  • Drink during every longer climb or rest break.
  • Replenish your fluids afterward.

Comparison

  • Short trail: water is often sufficient.
  • Long trail: take enough water with you.
  • Hot weather: account for additional fluid loss.
  • Mountain trail: plan your hydration in advance.

Scientific explanation

Trail running combines endurance exertion with changing conditions. As a result, your fluid loss can vary depending on temperature, terrain, and personal sweat production.

Practical checklist

  • Check your hydration vest.
  • Bring water.
  • Plan your route.
  • Know where the refill points are.
  • Hydrate afterward.

Common mistakes

  • Bringing too little water.
  • Not making a hydration plan.
  • Only drinking when you’re thirsty.
  • Underestimating the temperature.

0530 Expert Tip

Practice the same hydration strategy during training that you plan to use during a trail race. That way, you won’t be caught off guard.
