Eating better and exercising more are high on the list of a lot of people's New Year's resolution lists.
But while most are quick to forget their New Year vows, one Melbourne couple has stuck to it, every single day of 2013.
Alan Murray and Janette Murray-Wakelin, originally from New Zealand, have spent the past 365 days running a marathon every day around Australia, eating only raw plant-based foods.
Today the couple, who are both in their 60s, made their triumphant return to Melbourne one year and 15,500 kilometres later.
"It feels great, we always knew we could do it, but just the feeling over the last couple of days knowing that it was going to happen is good," Mr Murray said.
Adventure is not foreign to the couple.
In 2000 they ran the length of New Zealand - a mere 2,180 kilometres. Before that they sailed their 40-foot yacht across the South Pacific.
But the latest accomplishment has proved to be the pair's greatest feat.
At the age of 52, Ms Murray-Wakelin was diagnosed with breast cancer, and doctors gave her a year to live.
A decade on, she is promoting her natural lifestyle as the key to her health.
"We're eating fruit mainly - nothing peels faster than a banana, lots of greens, carrots and beets," Ms Murray-Wakelin said.
"That's pretty much it, that's got all the nutrients we need to get the energy we need to stay healthy, not be sick, and be able to run a marathon every day."
A typical day on the road
- Up at 4:00am
- 10 bananas, a grapefruit, and a date smoothie each for breakfast
- 8:00am: Make room for another 10 bananas each
- 9:00am: Large green smoothies to help wash the bananas down
- At 30km, stop for a fruit salad
- Three oranges each at the 37km mark
- Finish marathon around 4:00pm
- Vegie juice, avocado and a huge vegetable salad for dinner
The running has taken the pair to all parts of Australia, and they say it is the people they have met along the way that will stick with them the most.
But there will also be a few other things they will not forget.
"We had our crew drop our lunch off for us one day and when we got there, there was a dingo munching away," they said.
"We joined him, if you don't mind, so he finished up his banana and went on his way."
The gruelling adventure is not quite over for the couple.
They plan to run from Melbourne to Warrandyte tomorrow to set a new world record for most consecutive marathons - 366.
