Just wanted to say thanks for doing these. I bike all year but generally don't log my biking in the Cycling Challenges from April-October because those are the easy glorious months (IMO), rain or shine. Here in the Great White North, conditions are only a challenge from mid-November through mid-March.
After a truly shitty day (e.g., snowstorm, -20 degrees C), recording it in the challenge sheet is just about the only fun thing to do, aside from swearing like a sailor during the ride, and putting the bike away at the end of the day.
