Right now I'm riding about 70 miles/week (for the past two months). But earlier in the year I was riding minimum 150mil/week. In June I had almost 800 milies.
I live in Irvine and commute to Costa Mesa via Newport Coast (or Back Bay) to PCH, then SART - 17miles. My return commute is via Main St (through Irvine) - 8 miles.
When not commuting, I ride with the OC Rebels on occasion. Those rides are mostly South Orange county routes. When I want a long (75+ mi), I'll loop through Santiago Canyon, climb Silverado, head back to the coast and turn towards home via Newport Coast. If I want a fast group, I hook onto morning Coffee Crew (in Irvine) or Sunday Como St.(Tustin) rides.
