She said the one bonus for past competitors was that they could now see that they actually did a lot better than they initially thought they had.
The event was dreamt up four years ago as a fundraiser by three parents from Havelock North Primary School - Ms Throp, Susie Devonshire and Rachel Cornwall and had since donated more than $13,000 to two earthquake-affected schools in Canterbury.
It had grown to the point where last year it attracted more than 600 entrants.
The fourth Peak Trail Blazer will see the return of the always hotly-contested Aesthetic Dental Queen of the Peak and Quarter Acre Wines King of the Peak with each winner bagging a $400 cash prize.
"We're really excited to see who comes out of the woodwork this year to try and claim the titles and take home the cash," Ms Throp said.
Last year's event was the first to offer prizemoney and she said the organisers were "blown away" by the speed of the contestants.
"We wanted a sprint race and that's exactly what we got."
Part of the event, which had proved popular, had been the introduction of the Sub-60 Hall of Flames Club for competitors who competed the Te Mata Peak course in under an hour.
It currently has just 10 members.
