The 38 year old from Gunghalin has her hands full with her gorgeous seven-month-old baby Daniel.

However, having the goal in April to get through the race pushing her little one in the pram has been a great motivator.

"I did an event in September of 2015, but when I had Daniel I absolutely stopped running and exercising," she said. "The idea was to register for this run to discipline myself and build up a routine again."

She hopes to be feeling fit enough to run the full distance but said having a plan B was always necessary with children around.

"I will run with a friend so if it is too much for me to handle, I can get them to help for a while," she said.

"Daniel usually feeds around the event time so if he is crying for his milk, we will all have to run!"

To build up her fitness she has been heading to Yerrabi Pond and using a smartphone app to track her distance and timing.

In past races Ms Teng enjoyed the atmosphere and said she hoped there would be cheerleaders scattered around the course this time around to take her mind off the task.

"Seeing all the people in their costumes and being part of the atmosphere is so entertaining," she said.

"Last time I did it they had something going on nearly every 1km, plus the weather was really good. I come from Malaysia where running can be torturous because it is so hot. So hopefully the 5km is not too bad."

Her early months as a mum has taught her to keep plans loose and so she has cast aside the concept of a target time.

"I usually have goals but that is quite impossible at this moment," she laughed. "If I can reach the end line without passing out that is good enough!"

Participants wishing to compete with a pushed wheelchair or stroller must enter into the Orange Start Group for the 10km event or the Yellow Start Group for the 5km event.
