Grant Thornton GT5K

The GT5K Corporate Challenge is back with events in both Cork and Dublin promising to be bigger and better than ever!

The 2023 GT5K dates are:

  • Cork, Kennedy Quay 13th June
  • Dublin, Docklands 26th September

Over the last number of years the absence of social work events has been largely felt. The GT5K is back to help workforces to stay active and healthy while also enjoying some social team building.

GT5K 2023 invites corporate teams, family teams, sports club teams or the individual runner to take part and compete. Teams are made up of 4 runners, with team categories of male, female and mixed. This year there is also an option to run as an individual! All races will start at 7.45pm.

When you register, you will receive a sustainably conscious GT5K t-shirt to add to your collection – or start it!
