My commute is 22 miles each way, largely on bike/running trail along the Santa Ana River. The are two parts that need more attention..crossing the entrance to the freeway on-ramp and crossing one very busy street that has good lights but lots of red light running cars. On the way in, I end by going through the parking lot of South Coast Plaza and then the Orange County Performing Arts Center.
Do you do that distance 5 days a week? Impressive if so. That's twice what I ride and I get tired if I do mine several days in a row.
