quick question - i'm thinking about going to hellyer on sunday to check out the race my friend's doing in the afternoon. i don't have a car, so i'm taking caltrain there and bike from the station. i think caltrain's last station on weekends is san jose downtown, and i was wondering how long it would take from sj station to hellyer if anyone has done it. i'm trying to plan my trip and unsure which train i should catch in order to not miss the race.
