And no, I doubt there are very many mature cyclists on Lit.
Let alone a single mature woman cyclist in Sacramento ... kinda throwing my message in the bottle out into the local tide pools and hoping for a return....
As Judy Tenuta used to say, "Hey! It could happen!" *G*
Sacramento is blessed for cyclists. There is a flood plain that runs from the town of Folsom down into Old Sacramento .... The area between the dykes (I know, I am probably setting myself up with that particular noun in here) is riparian for the most part. So they paved a six foot wide trail that runs down the side of the river and makes an excellent riding and commuting trail.
That sounds flat. I'm from WV, I don't know flat. Flat = no mountain biking. Flat is ideal for unicycling though, since you have to pedal downhill on that 1 wheeled fixy.
We have the best of both worlds. Sacramento is FLAT! We in fact are 14 feet above sea level.... but 45 minutes away is Squaw Valley in Lake Tahoe. The summit just before Lake Tahoe is 7200 feet.
In the area just South of Lake Tahoe, there is a century called the Markleeville Death Ride. www.deathride.com Like the website says, 15,000 feet of climbing over three alpine passes, the least of which is 8300+ feet. And no, I not only have never ridden it but have no intention to do so. *S*
On the other hand, there is the Stockton Century. I would guess that the ride has a total climb of perhaps 500 feet. And that is done climbing the dykes down in the California Delta. http://www.sbclub.org/sbc/delta_century2.htm
Many many years ago, a bike shop that I worked in had a modern Pennyfarthing.
It was used mostly as decoration. But a friend and I greased up the bearings and took the Pennyfarthing and my road bike on the Stockton Century. It was really fun to see the look on the tomato truck driver's faces when a bicyclists face showed up in their side window..... talk about a double take!
Haha, I know the feeling, I ride my 5'5" giraffe unicycle which puts my head around 8 feet off the ground.
15,000 is a bit much, but its not so much. I race for a university team and our conference champs race was 32miles long with a little over a mile elevation difference. And that was for the easiest class. The poor Cat 1,2,3s had to to 2 laps.
As long as you're not trying to get your century in under 5 or 6 hours, you can do it, just pace yourself, and eat.
Just remember, after all the climbing, theres that sweet downhill- just too bad the downhills are shorter than the ups.
