THOUSANDS of runners are preparing to take on their favourite steam-powered rival, Puffing Billy.
Entries for the Puffing Billy Great Train Race opened early February but are still available.
Now in its 35th year, the event will see runners compete against the icon as it steams through the Dandenong Ranges.
Competitor numbers are expected to hit 3500, who will take part in the 13.5km race from Belgrave to Emerald Lake Park on Sunday 1 May.
The Great Train Race is one of the oldest and most popular events on the Australian running calendar, with runners pitting their fitness against the popular tourist icon.
However, it’s not just the steam train with which runners need to contend.
The varying terrain of sealed and dirt roads will provide an extra challenge as runners traverse the hills of the Dandenong Ranges.
Puffing Billy Railway special events manager Matt Collopy said the first 10km of the race would be an uphill battle.
“The Great Train Race is a very challenging run and not for the faint-hearted,” Mr Collopy said.
“While relatively short in distance, the three hill climbs in the first 10kms certainly test the runners and we encourage all participants to train accordingly.”
This year, North Balwyn speedster Steve Kelly is preparing to set a new record and be the first person in history to win the race four times.
Kelly won the event last year in a record time of 42.27s.
He previously won the race in 2012 and 2013.
Event organisers are expecting a sell-out within seven to 10 days of entries opening, so runners should sign up quickly.
All proceeds and any additional donations go towards the Puffing Billy Menzies Creek Museum Redevelopment project.
