He had never done this before but wanted to use it to prepare for June's tour as well as raising awareness for the Mental Health Foundation.
"It's a worthwhile charity, mental health is under-serviced and under-funded."
He will be part of a team of eight amateur cyclists from New Zealand taking on the Tour de France experience with a goal to collectively raise $25,000 for the Mental Health Foundation.
They will be starting in Northern France before heading south to the Pyrenees across the Alps and finishing in Paris.
The group will get close to experiencing what it is like being part of a pro-team with tailor-made training, nutritional plans, a team bus, service vehicles, a dedicated mechanic, massages and team support.
Because the riders will be going a day before the race they will also get to cycle through the towns and villages decked out with Tour de France paraphernalia and lined with fans.
The group met in Christchurch for a five-day training camp at the end of April, cycling more than 700km with former Olympic rider Hayden Roulston.
