Hey, are any of you people Hellyer riders?

I ask because I'm gonna be visiting San Francisco from 9/29-10/5 and I hope to make it down to the track for some training.

But, I'm car-less so I'll need to use public transport. Can anyone tell me how to do this? I hope to make the Thursday and Saturday morning sessions, so I also have to make it there before 8:30.

Thanks much in advance
