"The majority of the group wouldn't be cyclists. Most of them are ex-rugby players who've got older, put on some weight, found a cause, and got fit again."
Mr Nicholas said last year, during the South Island tour, the group lost over 150kg collectively.
As well as raising awareness of depression, suicide and anxiety, group members are fundraising for local charities as they travel through.
"Last night in Waverley we had a quiz night and we raised $2000. That money stays in the local community."
The South Island ride raised $170,000.
