Old Cooperians director of rugby Andy Yarrow said: "I couldn't be prouder of my boys.
"On paper we had players missing but such is the depth of our squad now you wouldn't have known it.
"I told the boys after the game that my personal target for this season was to finish top three, but despite the loss I actually feel we can push on from here as a title contender.
"We must continue to replicate performances like this.
"That being said you have to credit a well drilled Harlow side, you can tell why they will be battling for promotion this season."
Old Cooperians now have a week off before they head to rivals Campion on Saturday, October 16.
