Yes! You will need to register on the Melbourne Marathon website for the particular race event that you are entering e.g the 5.7km.
This is separate from your fundraising page - both need to be made.
The registration cost ranges from $40 (cheaper for under 16s) to $155 depending on the event you are entering.
Unfortunately, as a small organisation we don't have the capacity to pay for everyone's registration up front. However, we will reimburse half of your registration cost if you fundraise $300, and all of your registration if you fundraise $500.
