"Whether that will be reflected in a larger walk up, I don't know," Charnock said.
Damage from the June floods to the walkway along Anzac Parade, across the road from the Red Lion Hotel, and at Kowhai Park, initially had the course in doubt for this year's event.
However, the Harriers club was able to work with NZ Transport Authority, Whanganui District Council and Loaders contractors to ensure today's event followed close to its traditional course format.
The full marathon and three-quarter marathon walkers, who do three laps, will depart first thing this morning at 6.30am.
Marathon and three-quarter marathon runners will be off at 7.30am, with the quickest of them looking to complete the course just under the three hour mark, with last year's winning time being around 2hr 50m.
At 8am it will the half marathon walkers who leave, followed by the half marathon runners at 9am.
The 10km run - once around the course goes at 9.30am, followed right afterwards by the 5km runners, who just follow the Dublin and City Bridge loop.
The start/finish is across from the Union Boat Club sheds on Somme Parade.
Entries can be taken on the day up to 30 minutes before events start.
