"There will be some moisture on the ground but given that Hawke's Bay hasn't had a lot of saturation in the last couple of weather events I would expect there wouldn't be much surface moisture left," Mr Kandula said.
Last night's low dropped to 8 degrees and Mr Kandula added that by the time the marathon kicked off the temperature would still be relatively cool.
The running festival, comprising a marathon, half marathon, 10km and 3km kids' race, is set to take in the region's highlights with the course tracking through cycle trials, vineyards, olive groves and country roads.
The main event is scheduled to start at 9am on Marine Parade, Napier, between Edwardes Street and Sale Street.
Those enduring the race will pace past picturesque views and spend the last 10km running through private vineyards before finishing at Sileni Estates Winery.
Anyone who finishes the marathon will receive a finisher medal and those who place 1st, 2nd and 3rd overall in the mens and womens races will receive $3,000, $1,500 and $750 prize money respectively.
Marine Parade, Te Awa Ave, Eriksen Rd, Awatoto Rd, Brookfields Rd, and Twyford Rd will be closed throughout the day to accommodate runners.
