Yes! You will need to register on the Melbourne Marathon website (or another event of your choice) for the particular race you are entering, e.g. the 5km run.
This is separate from your fundraising page - both need to be signed up for.
The registration cost ranges from $40 (cheaper for under 16s) to $155 depending on the run 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 raise $300, and all of your registration cost if you raise $500 (or more).
