The training buddy is a super source of motivation, especially when your will to train is weaker than your desire to eat/sleep/generally procrastinate etc.
I managed a near 2 hour bike ride, whilst putting the world to rights, with my friend last night. Barely noticed the hill she insisted we ride up at the end.
My running chum texted me yesterday too. "Oh no, I'm double booked!" I thought. Only to open his message and discover he wasn't trying to arrange a run, but was announcing the birth of his new baby son instead. Hooray! Congratulations! Let us celebrate with cake!
All hail the training buddy!
