The GOW course is largely unmarked for this race but is very easy to follow with clear Parks Victoria signage and some additional flagging tape and arrows where required.

The course .gpx can be downloaded at the bottom of this page and links here to Garmin Connect and Suunto Movescount (updated September 2017):

The new signage that has been added along the full length of the course means there will be very little supplementary race signage. Basically every junction is clearly signed. Follow the yellow arrows on the timber posts and check the green metal distance signs and you can't go wrong. The green signs have the GREAT OCEAN WALK clearly labelled. The signage looks like this:

NOTE - COURSE CHANGE FROM 2017 (same for 2018):  NO CREW are allowed into Blanket Bay and runners do not go through the campground anymore (following complaints from campers). Instead, you will traverse the beach to the southern end where there will be signage and hopefully a marshal to direct you up a ramp straight into the new checkpoint in the day visitor car park and picnic area. There are toilets here if needed.

The finish line is now at the back of the 12 Apostles carpark. This means you now swing right as you pass the kiosk and follow the markers staying on the right-hand shoulder of the carpark all the way to the back. Through the opening onto the grass, across the helicopter entrance (be careful of tourists here) to the gantry.

With ongoing track realignments some of the distances below will be slightly inaccurate. This is a trail race and not a certified measured distance. It means more primo-singletrack and less gravel road. We are now off the road at the finish, using a tunnel under the road at Gibson Steps and new trail to the visitors centre. There is a new section of cliff-top singletrack on the approach to the lighthouse; you no longer go up to the road and follow the road. Wear your fluoro vest through the carpark.

You can download this great app onto your phone and with the course loaded it will show exactly where you are, on or off the course. This is a great way to check if you are not sure of where you are:


The run follows the established Great Ocean Walk track which is well signposted. 
While the official Parks Victoria distance for the walk is actually 105km, previous race measurements indicate this is closer to 100km. In the spirit of running the official GOW track from end-to-end, there are no deviations or add-ons. This might mean the distance traveled is slightly less than 100km. Or it might be slightly more than 100km. Being a true trail race there will always be variations in measurements and the distances listed below are to be used as a guide only.
There are numerous junctions and camping grounds along the Walk that are generally very well signposted. Stop and look: you do not leave the trail to go into any Hike-In Campgrounds. Be aware that you should never be on a beach after Milanesia (65km) and never on bitumen apart from in the Otway Lighthouse carpark and the 12 Apostles carpark at the finish line. Do not run on a bitumen road. You are in the wrong place.

While there will be some supplementary course marking, runners are expected to be able to navigate the course following their map, and the Parks' signage. There are almost no junctions that are confusing anymore. Only a very few will be marked with GOW100s race signage. An example of these will be demonstrated at the race briefing. Given that the course follows the coast fairly closely for most of the way navigation is relatively straight forward. The trail does pass through areas of dense rainforest and getting off course could pose considerable dangers here. If you miss a beach exit at any stage and find yourself on rocks at sea level going around a headland, go back as there are no dangerous places like this on the course.

This is a closed course. This means that the established trail must be followed. There should be no cutting the course, no cutting switchbacks, and no detours that would shorten the course. If a runner gets off course they should retrace their path until they return to the official course before continuing under their own effort i.e. do not accept a ride in a vehicle back onto the course as this means disqualification.

Course Notes

It has been decided that course notes will not be provided for this run.  There are ample existing course markings, plus minimal additional signage will be added for the race itself.  The following link provides information from Parks Victoria on the details of each of the course sections, as well as information on the 'decision points'.  At each of these the inland route must be taken. Runners are responsible for familiarising themselves with the course. Failure to complete the full course will result in disqualification.
