Tips For Intermediate Runners

Train With Purpose

Every day, every run matters. Don’t skip any of them.

Fuel Like a Champ

Nail your hydration and nutrition strategy early.

Track Your Progress

Use a running app or journal to monitor pace, distance, and recovery.

Smart Gear = Smart Running

Shoes like the Endorphin Speed 5 or Triumph 23 deliver the cushioning and responsiveness you need for long distance training.
