Seventy years after cycling 1300km from Hastings to Invercargill as a fresh-faced 17-year-old, Bill McGavock is endeavouring to repeat his marathon ride.
This time the 87-year-old is being accompanied by his 60-year-old son Steve.
Mr McGavock senior, from Havelock North, cycled through Wairarapa on Tuesday and camped at Clareville showgroundson Tuesday night.
He had no reservations about taking on the gruelling cycle, as it was something he wanted to experience one more time.
"I did it with a friend when I was 17 and I thought I'd like to do it again before it's too late."
Mr McGavock said he was fit and healthy and up to the challenge.
The duo have already completed about 230km and both father and son said they were feeling good so far. They expect to reach Invercargill in about three weeks' time.
Mr McGavock said he was never a racing cyclist or took his cycling too seriously, however, he had always enjoyed a good challenge.
