Agreed, not that big of a deal. Hamilton is definately no Haleakala.

I would mention when descending to be careful of cars passing ascending cyclists on blind turns as I've seen that happen plenty on busier weekends. Also, I know it adds a little bit of weight, but I'm partial to insulated water bottles--cold or at least cool water--can make a real difference in the enjoyment of the ride over warm plastic water.

I use arm covers also to protect my skin from sun exposure.
