The word 'terrier' comes from the Latin 'terra,' meaning 'earth' - so this year channel your inner earth dog and ride as far as you can. Reach the goal to collect your badge, and if you start feeling fearless and lively, then the transformation is working!
You have until December 31, 2018 to complete the challenge.
IMPORTANT: Registration is required. You MUST click "join" before riding or your totals will not count.
