I made my own bike journal in Adobe Illustrator. The front page is a calender of sorts that I can mark off the days I ride (and what bike), with room for weekly and monthly time totals. The rest of the book is full of pages with room for all the info I take from my speedometer and heart rate monitor, and a few lines to describe the ride, and some lines for general notes. It's wire bound with a mattboard cover.

It took a few hours to set up in illustrator and about $8-9 in material/kinkos costs. I made one for my dad as well, and it seems to be working for him too.
