Oh, don't give up so easily! Did it seem too long? It will get easier, and don't feel you have to do it every day, or even do the whole thing. You could drive part way and bike the rest. As for the rain - did you stay warm enough, or do you need to get rain gear? Or just pay closer attention to the forecast if you don't want to ride in the rain. But if you do, definitely get fenders.

Needless to say, lots of other good tips are all over this forum, or start your own thread if you have specific questions or just need encouragement. We'd like to see you succeed.
