Clip in sports fans, between the weather and the Amgen Tour of California (TOC), it's going to be a great weekend for cycling in the Bay Area.

Whether you're tackling Mt.Tam on your Saturday morning club ride or comparing yourselves to the pros with a summit of Stage 3's infamous Sierra Hill climb, pack the sunscreen today and leave the rain shell behind.

On Sunday at 1:00 p.m., the TOC starts with the prologue, a 3.0 kilometer time trial from the Ferry building to Coit Tower.
