Paeroa to Hamilton

Hauraki Rail Trail to Te Aroha, then highway with decent shoulder. Warm but not too hot. Headwind that continued to pickup during the day. 

I made my first costly mistake today. I lost my helmet. At some point I stopped for a break and took it off, and then somehow rode off again without putting it back on. Is this age related forgetfulness?

Wonderful Warm Showers host Heather in Hamilton. Tomorrow the train to Wellington.
