The event brings runners from across the board, including elite runners and those looking for some spirited exercise, which sold out this year for the second year in a row.

Speaking to Sunrise immediately after the win, Heyne looked surprisingly fresh after his 40 minute and 33 second effort.

This is the second year in a row Heyne has won the event.

Heyne said: “I’m pretty gassed.

“It’s a hard course so just let the pressure value loose.

“(It’s a) bloody hard (run). It’s nice when you’re running by yourself because you can control your effort.

“Sam (Clifford, competitor) is such a class athlete, so to have no idea where he is adds that level of pressure as well.”

Heyne, a champion runner, failed to beat the 1991 record held by Steve Moneghetti, but looked undeterred.

“I think I beat last year’s time by 20 to 30 seconds, so yeah, that’s a sign I’m in shape.

“It’s really promising. Maybe the record can wait another year.”

Following the race win, Henye said it would be indulging in some fast food.

“I’ll go home, have a nap, have some Maccas (McDonald’s) and then pick-up my girlfriend from the airport.”

Samuel Clifford came in second and Thomas Do Cato came in third.

For women competitors, Caitlin Adams came in second and Ruby Smee third.

The last group of runners left the CBD at 9.27am with the expectation the race will end at 1.50pm.

City2Surf is the world’s largest fun run and has raised $59 million for charity since 2008.

This year, more than $3.5 million was donated to support 600 charities.
