Started bike messengering in 1996, since 2000 as a parttimer. I work three days a week at the department for urban architecture in Amsterdam. The other day(s) I'm testing the urban designs with my bike as a messenger. I love this kind of parttiming. Good for brains and body.
About the 24 hours: I have started all 6 times, finished 4 times. Strangely enough the first 3 attempts on my trackbike were the best ones. In 2010 no race for me, i'll be your dispatcher on this years Labour Day. Enjoy and have a nice ride!
