We have , on occasions, done what we call "around the block". It involves doing a circuit from Christchurch,(here in Canterbury its hot and dry plains being the East coast of the main divide) up thru the Lewis Pass, down thru the Rahu Saddle to Reefton on the west Coast where the whole world has changed in the form of Native bush,streams,fresh air and beauty ....lunch there and on down the Island, thru Moana and alonside lakes thru to the Arthurs Pass...Native bush, rivers high mountainous country, back onto the Canterbury side now nd home. It's around 800 kms and a great days ride. Usually leave around 8.00am and home about 5.00-5.30pm.
