How long is a piece of string?
When I speak to most people about a bike tour of the South Island, they recommend 10 to 14 days if not more. I had 7 days of leave available and a small window of opportunity before the weather turned which I am told is in late April. To miss this window would be to delay the trip to later in the year or, a more likely scenario, next year. Riding in the South Island during the snow season can be very dangerous for bikes and the snow can come until as late as October/November. So with my biker comrade, we decided to make hay while the sun shines and ride as far South as we could in 7 days including the return trip.
