Hey Aggie, just don't even think about whether or not you'll stick to part-bike work commuting. Just go with the flow and do it on the days when you want to/weather is ok/workable for you.

I try not to be hard on myself on the days that I don't part-cycle during my work commute trip if the weather is quite rainy/very cold/etc. because I work so far out and it is a convoluted, time-intensive trip 1-way that blends in commuter-train, cycling, bus transfer and walking to & from workplace.

And for the days that I do commute-cycle, it's just a great way to destress and justification for my health,..a very long work-commute.

By car, I believe it would be 1 hr. one way.
