"Everyone is starving for a race after the winter," he said.
Hamilton said the James Dodds Memorial Trophy had become a prestigious award in recent years.
He said Dodds was well known in Rotorua as a track builder and bike manufacturer and was really involved with the Rotorua Mountain Bike Club.
He said he also helped out with junior riders at Descend Rotorua. "The award has a lot of kudos attached to it."
Rotorua riders Keegan Wright and Connor Hamilton will also be racing today, the pair fresh from their top-10 finishes in the men's junior category at the world downhill champs in Norway earlier this month. The pair both finished in the top-10 in the men's junior category this month.
The New Zealand Downhill series includes five stops and is the first big series of the New Zealand downhill season.
The next four events will be held in Wellington (October 11), Napier (November 1), Taupo (November 22) and Auckland (December 13).
