Multimodal commuter here too. Total commute is 30 miles each way. Driving it during rush hour takes 1.25 to 1.5 hours (and sometimes longer if there's an accident).

These days, I ride a 1/4 mile from home to the the MetroLink station, ride the Metrolink for 14 minutes, ride 3.4 miles from the MetroLink to the Green Line station, fold the bike, ride 22 minutes on the Green Link train, then ride the last 1/4 mile to work from the Green line station. Total commute time is 1h9m, plus or minus 7 minutes for slack time waiting for the second train.

I'm loving it. SoCal weather is a blessing...
