The full distance version of the BIG5 Challenge is the ultimate test of speed, stamina, and skill. Prepare yourself to be pushed to your absolute limits, physically and mentally.

Over 150km will be covered by those who manage to complete the BIG5 Challenge. From a brutal 80km mountain bike to finishing with a half marathon in the forest and all the running, swimming, and cycling in between.

The 2019 event sees the BIG5 Challenge capped at 100 athletes so we urge you to enter as soon as possible in order to avoid missing out!

All of the BIG5 Challenge athletes enjoy a one-stop registration process, preferred seeding, and separate awards ceremonies. BIG5 Challenge participants, and their families, will also have access to the exclusive BIG5 Hospitality Area.
