Back to Gold Coast
Surfers is a very Urban area with a lot of tourists and nightlife and fast food. About the best place to run is along the beachside promenade pathway. A wide path fronting the sand. Just go as far one side as you care to go then turn around and come back. Mix it up by running on the sand and make sure you have a dip afterwards.
Starting from the the main mall (Cavill Mall) its easy to get in up to 14km without even thinking.
