Bikerz,
Congrats, you're doing real well. I've eyed that trail from the freeway, looks interesting.
Some of my favorite places to ride that are relatively flat are:
* the Bay Trail on t'other side o' the bay starting at Foster City
* Alameda Creek Trail is a favorite and can be hilly or flat as you wish
* Bike Sundays on La Canada road - Velogirls bike club has established a Mello Velo ride on that one now each Sunday
* I haven't done the Iron Horse trail except for the portion that's on the Cinderella but it's on my list of things to do.
Anyone else got ideas? I'm starting to get feeling in my legs again ;-)
Always up for an EZ ride.
Also, you don't have to be a little-tiny-eetsy-bitsy-skinney-thang to excell at hill climbing, fact is your weight could even help as I'm sure much of it especially by this point is muscle. Climbing well I think is partly pure physical strength, but also technique, and psychological. Sometimes you just have to think your way through the climb (see cycling affiramtions thread somewhere here).
I saw plenty of big gals and guys on this last ride flying uphill past riders who looked like they were built to climb hills.
