How much saddle time do you currently have commuting? What kind of bike are you riding? Have you test ridden the route?

It's doable, but not for the faint of heart which is why I ask. I frequently do 30+, but my usual is right at 25. Even two days a week (I do 4-5) will have issues and best case scenarios, so a bit more detail about the ride and your conditioning would help.
