Got any other details? What route? How far? Thanks!
The start is where Kuamoo road crosses the stream at the Arboretum — at the Kuilau trailhead.
Basically it's up Kuilau, down Moalepe, down Olohena Road to Sleeping Giant, across the back side of Sleeping Giant to Kuamoo Road, back through the neighborhood and up Moalepe then back down Kuilau to the stream crossing.
The distance, maybe 12 miles? I'm not sure...
Chris at Kauai Cycle is putting it on so you could call or stop by the shop in Kapaa for more details. Last year was a lot of fun (maybe like 20 riders showed up, hopefully this year there will be more).
