"It's going good," says Tom Korakis, somewhere on the Pacific Highway, south of Taree in New South Wales.
When not in the saddle, Tom, with his brothers, runs one of Sydney's major supermarket distribution companies. With a love of cycling from an early age Tom rode racing bikes at the Lidcombe Auburn Cycling Club, where he was club secretary for five years.
By the time we talk, late morning on Day 3, Tom and Olga have covered 320 kms and are on track to get to Brisbane as per their carefully planned schedule. Arriving in the Queensland capital on April 9 will enable them to catch a flight the following day to Los Angeles for the US leg of their journey.
Challenges so far?
"Carrying a 23 kg load is the major challenge, and some of the roadworks along the Pacific Highway makes it difficult sometimes, otherwise it's been really good so far."
Though the intention was to avoid highways, says Tom, the weight of their loads combined with the benefits of cycling straight, means that they will have to hold their own alongside the roadtrains on the major interstate roads as they head north.
But the journey, even though in its infancy, has already attracted generosity from well-wishers along the way.
"You have to have a good night's rest before you head off on the next stage," says Tom, " but even in the first few days, people have been really lovely. When we stop along the way and tell them what we're doing, the hotel may be $100 and they give us $50 off as a donation."
Tom is keen to point out that as well as individual donations, any kind of business sponsorship would be warmly welcomed and can be incorporated into the American and European legs of the journey.
It's not the first time Tom has gone out on a limb for others in need. Two years ago he cycled 800 kilometres across Thailand to raise money for children made homeless and orphaned by the 2006 Tsunami. But this ride to Greece, covering around 1200 kms dwarves his first charity ride.
Tom and Olga will arrive in Los Angeles on April 11, before taking 47 days to ride the 5000kms across the United States.
After pausing for breath in the Big Apple, Tom will then journey on to Lisbon on his own to begin the final 5,500 km European leg. His route will wind across Portugal, Spain and France and head down through Italy, before crossing Greece's border at Igoumenitsa.
Before finishing the journey at his birthplace, in the village of Richea in Laconia, he will stop in Ermione, Argolis, to take part in a modest ceremony that will be attended by ELPIDA's founder and UN goodwill ambassador Marianna Vardinoyannis. At Ermione, the total funds raised during his journey will be revealed. The target set is $1 million and all proceeeds will go to help Greek children suffering from cancer and leuakemia.
With more than 100 days of cycling across the globe in front of him, Tom is optimistic that as more people become aware of the journey and its cause, the target can be achieved.
