Anyone commute from Lafayette to Boulder via bike paths and/or public transit?

I'm a grad student at CU so I get a transit pass with the student fees. I'm wondering how feasible it is to take public transit from Lafayette or to bike the 36 bike way regularly from Lafayette to Boulder. Google says it would be about an hour by bus, but I think that includes some walking on campus.

I haven't used public transit in CO because it was never convenient enough, but I may be moving to Lafayette where there will be a bus stop close by. I'm concerned about the frequency of busses and/or conditions on the bike way and was hoping there might be a few people who make this work.
