Deep RiverRock 

As Northern Ireland's favourite water brand with its roots in Tullynacross, Co. Antrim, Deep RiverRock celebrated their 10 years partnership with Belfast City Marathon in 2016, which has seen an impressive 168,243 participants covering over 4 million miles since Deep RiverRock came on board as Title sponsor in 2006. 

Deep RiverRock are delighted to be involved again in 2019.


With a shared vision - to encourage more people to lead active and hydrated lifestyles - the partnership with Belfast City Marathon continues to be a perfect fit for Deep RiverRock, as the number one water brand on the Island of Ireland.

Deep RiverRock is honoured to have played a part in the success of what is now a key sporting event in the Northern Ireland sporting calendar. Over the last decade, Belfast City Marathon has evolved to become a not-to-be-missed family day out with something to suit all ages, fitness levels and lifestyles. Now with an 8 Mile Walk, a Fun Run, the full Marathon and much more besides, the event has captured the hearts and minds of the community.

With the mantra, "If you can't think straight, HYDRATE," Deep RiverRock knows that a 2% drop in your hydration level will slow your body and mind. That's why we have worked tirelessly over the years to ensure that all participants of Belfast City Marathon can stay focused and hydrated throughout the day, so they perform to their best.

The team at Deep RiverRock would like to thank all participants, supporters, organisers and volunteers who have made this event what it is today, and we look forward to a great event in 2019 and beyond!
