All entrants into the Strava challenge understand that in exchange for their Strava challenge discount code and free gift, they agree to be added to the HUUB mailing list from which they can unsubscribe at any time. Only ONE free gift and ONE 50% off discount code per Strava Challenge completer is allowed, unless the challenge is completed on or before the 6th of June, when 2 discount codes will be issued. Discount codes expire on the 30th of September. HUUB reserves the right to revoke discount vouchers and/or exclude anyone suspected of not completing the Strava challenge or anyone who has claimed multiple vouchers.
