Facing down a winter of indoor training is less brutal when you’ve got good music. I wrote a piece for my friends at Wanderlust with suggestions on how music can inspire your training, along with Google Play channel recommendations (I truly do love Google Play’s curated stations).
Training for a swim-bike-run triathlon means many hours of repetitive motion. While you can’t race with music, it can be an enormous help as you train. And the songs that uplift you during your workouts can be useful in the race itself, as you can carry the music in your head to help you find the right pace at the start, keep a steady rhythm in the middle, and push through to a strong finish.
