The race had sold out within four weeks of opening, and the event's second release of entries had also sold out.
Farmer said he had enjoyed seeing people at the finish line and achieving what it was they had set out to do, whether that was chasing a time or just having fun.
"People were really happy, had their mates waiting for them at the finish line, were high-fiving and taking selfies."
He said they would definitely be looking to hold We Run The Forest at some stage during winter next year.
Participant Stacey Coleman said she took part in the 11km event and had liked the idea of the race being in the Redwoods.
"It seemed like a nice race to do. It's my first race back after having my second child."
She said it had been great, though was a little tougher than expected because it was a bit hillier than she thought it would be.
"But I liked it. It was a blissful race being in the woods."
Coleman said the Redwoods was the best place to run in because there were no distractions and it was peaceful.
She said it was a well organised event and she would "totally" do the race again.
