Bikejournal Question - Configuring Columns

One of my many New Year Resolutions for 2006 is to keep a proper training diary.
I've set up an all-singing, all-dancing spreadsheet, and will also track all my data in Bikejournal (well, that's the intention!).
When I moved to New Zealand, I finally converted to metric and now measure all my distances, speeds, etc. in kilometres.
Does anyone know how to configure the columns for an individual journey to read Kms instead of miles in BJ?
The blurb says you can enter either, but when you try and configure them, I only see the option for miles. I was hoping not to have to do a conversion for every entry into BJ.
Does anyone know how to enter Kms - if I just enter a figure, it's going to assume it's miles and although I'll look impressive, it won't be a true record!
Hope this makes sense!

Sorry guys, this is a case of not doing the research properly before posting the question.
Investigated BJ further and discovered you can select metric in the "Edit Profile" option.
Doh. :o
