I actually signed up this year, and I hope to get at least a couple miles every day.
There are schedule challenges with school/work/kids, and geography vs. time makes things tight for the bike.... alas, even if it means getting home at o'dark-thirty, tired from a long day, I still plan to get at least 30 minutes of riding, even if it's a quick errand. That's the whole thing: 30 days of Biking... just don't miss a day in April! While there will be a good dose of short rides, I also have 300 and 400km rides scheduled this month... so, it will be a little strange.
I also at least plan on a FB post-per-day, too... to keep track.
To those registered, and already enjoying day-two -- good luck!
