How it Works

1) Register for the Berkeley Half Marathon 5K, 10K, or Half distance (1K and 1Mile excluded)
3) Share your personal referral code or link with your friends, family or post on social media
4) They must use your referral link when registering, for either the half marathon, 10k or 5k (not valid on 1k or 1 Mile registrations)
5) Referral socks must be picked up at Expo or at the Finish Line Festival, check your bib for the referral sock stamp.

*Your personal referral code and link will be listed in your race confirmation email.
