Cycling Victoria will investigate a crash at Sunday night's Bendigo International Madison which resulted in one spectator and four riders being taken to hospital.
The incident occurred on the 62nd lap of the race, with one rider spilling over the fence and crashing into a spectator.
The spectator - Ross Forster,70, of Maryborough- was taken to the Bendigo Hospital with head injures, and was later transferred to Melbourne's Alfred Hospital in a stable condition.
"We will receive a report from the chief commissaire and work with the Bendigo International Madison committee on their event evaluation and how to further improve and bolster what we have in place for safety at our events," Cycling Victoria general manager Craig Eastwood said.
"We won't look to make any knee-jerk reactions.
"We will go through - as we are doing now - step by step an analysis of what happened, why and what tips we could look to in the future."
Three injured cyclists remain in Bendigo Hospital in a stable condition, and one has been discharged.
"Our thoughts and immediate concern goes to the spectator in regards to his health and wellbeing," Mr Eastwood said.
Mr Eastwood said he was pleased with the "speedy response" of the medics on site and race commissaires who immediately stopped the race.
"A speedy response is something we always focus on and deliberately positioned first aid responders at specific points around the track," Mr Eastwood said.
"There was an immediate protocol of calling 000 and we ensured multiple ambulances were called to make sure everyone was seen to."
For every Cycling Victoria event a review is conducted into "where we can do marginal gains to make sure we are providing a safe environment for all".
"It will take between two to three weeks to get all the information together, we will look to improve the safety at all of our events," Mr Eastwood said.
Bendigo International Madison secretary Rik McCaig said the group would await the commissaire's report, in regards to any changes that need to be made to increase safety of spectators and riders at future events.
"It was very unfortunate. Every now and then you see a crash involving multiple riders, it's an unfortunate side of cycling," Mr McCaig said.
"All our services were in place and they responded amazingly.
"We will be governed by what is said in that (commissaire's report), we will wait and see what comes out of it.
"There was a lot of concern by many people last night, it shows what a humble and respectful community we operate in.
"Everyone involved is in a stable condition which is a great outcome for an incident that involved so many people."
