But Threlfall's 10th win on Sunday was the pick of them as he celebrated the birth of his son Hudson - who entered the world just several days earlier.
In what has become a common storyline at the event, Threlfall blitzed the field in a stunning time of 31 minutes 15 seconds to score what he described as his best win yet.
“You feel like you are representing more than yourself in a way (when you have a child),” Threlfall said.
“It’s funny how having a baby at home does change your perspective of everything.
“I’ve been a bit sleep deprived, my back is a bit sore because I’ve been bending over changing nappies like you couldn’t imagine.
“It’s cool to think he can look his name up in the newspaper in 10 years’ time and say ‘that’s my dad who won.
“He hasn’t had all his vaccinations so I couldn’t bring him out, but I was definitely thinking about him as I was running.”
It was a similar story for mother Penelope Bennett who was the fastest woman across the line in the 10km event in a time of 41 minutes 51 seconds.
“Running the kids around to all their after school activities certainly helped me prepare,” Bennett joked.
“I wouldn’t say my training was too serious but sometimes getting the kids on the bike and trying to keep up with them certainly helped.
“It's great to come first but being able to compete in a community race is a great thing.
“I really love this type of race where all the funding goes back into the community.”
This year's race saw a reduction from 12.5km to 10km and Threlfall admitted it made the run much easier.
“When it has been 12.5km in the past it has been a bit of a weird difference but now you can compare it to the other 10k races that you have done,” he said.
“Being on dirt meant the track was a bit slower than others but I felt strong right throughout the race.”
He will now turn his attention to a half-marathon at the Melbourne Marathon Festival this weekend.
