Road my first metric century today. Created it by adding 22 miles r/t to the starting point for our clubs Long Distance Training Ride of 45 miles. So, 67 miles, 5120' of climb.
I learned I really want to swap out my 11-28 cassette for a 11-32 one. Yes, I'm a wimp, but I could not maintain a decent cadence on the higher grades. What good is a granny gear if it isn't granny enough?
Beautiful ride, up amongst the redwoods. Beautiful weather (well, except when the winds kicked up).
Also figured out I'll probably do our club's Half Century (56 miles, 5660' of climb) instead of the Metric Century (71 miles, 6990' of climb -- yes, our club is bad at math). It's only about a month from now. And while I suspect I could manage another 4 miles, there's no way I could do another >1800' of climb!
