But for Chris Gamble, a Canberra marathon runner, distance running is a way of life.

His Christmas holidays will be spent gearing up for his push towards his 100th marathon, which will be his home town race, the Canberra Marathon.

His most recent marathon, his 97th, was in New York and between now and the April Canberra race he will complete numbers 98 and 99.

Once he has completed the Canberra Marathon he will become a member of the 100 Marathon Club.

"Even after I complete this run I will still consider myself an apprentice runner and I look forward to continue running," he said.

With Christmas celebrations around the corner and overindulging in holiday feasts a given, Gamble had this advice for those trying to stay in shape.

"You can eat a whole turkey, but for every calorie you put in, you need to be able to put those calories out," he said.

"Marathon running is a lifestyle that promotes healthy living, a good diet and a positive attitude that you can use in everyday life. You see the benefits from it in your daily life and as you get older. But this can be said of all sports."

The key to a healthy lifestyle during the holidays was discipline and a daily exercise, he said.

The 2015 Canberra Marathon action starts on April 11 with light-hearted five-kilometre and 10-kilometre fun runs, with the marathon and ultra-marathon taking place on April 12.

Gamble had this tip for any first-time runners who were thinking about taking part in the marathon.

"Don't push yourself to keep up with others. Go at a pace that is comfortable for you," he said.

Early-bird entires are open for the Australian Running Festival and runners can organise fundraising to more than 180 charities.
