Route Linkou-林口 to Dayuan-大圓  

This is a nice typical ride down 106 with it's lovely curves going out towards the beach along highway 15. While head towards Dayuan, you can ride at speed with a minor uphill. Then turn-around at the major intersection via the underpass and do some more speed work coming back. 106 up the valley provides good slow work up with some really nice farm views in taking the valley back road back into Linkou. Kilometer 27 to 28.5 is probably some of the toughest climbing I've encountered yet on a group ride. Just short and steep. A granny gear for me, finally...
