Little Athletics kicked off its season at Dudley Cornell Park, Horsham on Wednesday.
Horsham Centre president David Panozzo said he was thrilled with the number of athletes who participated.
A come and try session had been cancelled because of wet weather earlier in the season.
Mr Panozzo said more than 100 people turned up on Wednesday.
"Complimenting a large quota of returning athletes, there were many new faces trying Little Athletics for the first time,'' he said.
Mr Panozzo said distances and times were not recorded, with all children encouraged to have a go.
He said all athletes had the chance to participate in four separate events, including at least one run, throw and jump.
Official recording will start this week.
Mr Panozzo said people could register online at the Little Athletics Victoria website.
He said people could get help with the registration by talking with committee members at Horsham Little Athletics on Wednesdays at 5.15pm or by calling him on 0408 504 988.
