Um yeah having a bit of a penchant for running and general fitness myself, I suggest definetly do some running in the town belt ie Tinakori hill for starters (full of groovy little tracks off the main ones and you could almost spend an hour exploring every nook and cranny popeyes' cave for one) . Along the waterfront, oriental bay and then up onto Mt Vic via Hay St and Telford Tce and generally running along and around Mt Vic's tracks. From Brookly up to the windturbine (via the roller coaster) and possibly up to Hawkins hill and out into happy valley via spooky gully, where you'll come out onto the road beside the tip and back to brooklyn. Ah there's heaps really.
