The ride focus is a little bit of uphill (to ensure you feel like you are doing something) to begin with, then a lot of downhill to finish. You can do this with the help of the support vehicle driving ahead to wait for you. Once you have conquered the climb you have an adrenaline pumping journey 8 kilometers downhill.
You will be met at the other side with a picnic lunch ready. Then there are a few options for the afternoon. You can walk up to the Punatangarua Pinnacles (as featured in Peter Jackson's the Lord of the Rings as The Paths of the Dead) Or you could enjoy wine-tasting at Martinborough's famed vineyards, drive out to the seal colony at Cape Palliser, visit a ciderbarn, the locomotive museum or just head back to Wellington with a downhill mountain bike from the Rimutaka summit to Kaitoke.
