I am going to start commuting to university by bike now. The train journey is about 40-50 minutes door to door.

Pros:
Allows me to keep fit without having to find time to cycle after I get back from university. The way I see it is, if I cycle into work even though it takes me a bit longer I wont need to go cycling outside of work to keep fit.

Ill be more awake in the morning (fingers crossed)

Cons:
I have commuted to work before, that being said the distance was shorter but my appetite for food shot through the roof so I guess that is a con.
