I personally like listening to something when im riding a track that i regularly ride. It seems to help me get into a mindset of being able to ignore leg burning, pain, or exhaustion and being able to focus more on the fun of riding. How about you?
I use regular earbuds, on my music phone (LG VX8300) What type of earphones and music player do you use?
I post this in MTB forum and not in foo forum since MTB presents unique circumstances than in general bike riding.
