Meet at 8:00 am
Pre-registration
This should be a relatively slow pace because I intend to ride on a bikeshare bike. However, regroups will be at the bottom, not the top. Tentative route: https://www.strava.com/routes/3509044319111941298. Most of these climbs have some pretty steep sections (extended 10+% or brief stretches of 15+%), some may be relatively unfamiliar (or hills you are more used to going down than up). Note there is a dirt descent at the end but that can easily be avoided. This is all local and easy to bail at any time.

Here are all the hills:
Loop 1: Shasta Road, Canon Drive, down Spruce, regroup at Shattuck and Vine (Cheeseboard)
Loop 2: Up Cedar+Buena Vista Way, down La Loma+Cedar, regroup at Shattuck and Virginia
Loop 3: Up Virginia, La Loma, Glendale, Campus, Avenida, Senor to Grizzly Peak Road, down Centennial, regroup at College and Bancroft.
Segment 4: Up Centennial all the way to Grizzly Peak, back down to College and Bancroft
Segment 5: Panoramic-Dwight, down Panoramic, regroup at College and Derby. This is the shortest segment but Dwight Way might have the steepest bit.
Segment 6: Up Claremont, down and up Fish Ranch, down Claremont, regroup at College and Russell
Segment 7: Up Alvarado, Drury, Strathmore, Marlborough Terrace to Grizzly Peak Blvd, left, down Claremont, regroup at College and Russell
Segment 8: Partway up Tunnel, left on Charing Cross, Down Hiller, regroup at Rockridge
Segment 9: Up Broadway Terrace, down Dirt Tunnel (or continue on the road), finish at Rockridge

More details to be shared later
