I've just joined the challenge. I'm a pretty beginner cyclist but getting more comfortable with it. I'm loving my new strategy to get around my chronic lateness in the morning that stops me riding into work. On the day i take DD to school, I have to be late to work no matter what I do (drop off is after work start time) but that means I can take the bike on the train. So take bike in on Tuesday, ride home on Thursday. As I get faster with the riding I should be able to ride in and home on Fridays too, but that's a stretch goal at the moment.
For now I'm just enjoying the sunset over the river, trying to race the cars on the freeway (they are beating me but not by much, traffic is pretty slow in peak hour), and meeting by killer hill goals. First it was getting up without stopping and having to walk the bike, then it was getting up without having to go down to my very lowest gear, next I'm aiming for keeping my speed in double digits. Slowest I got today was 8.5kph, so I'm nearly there. My other short term goal is to average over 25 kph on the long flat section of my ride, and long term goal is to actually overtake someone for once! (Most of the riders on my route are in lycra on proper road bikes, so in my casual gear, with baby seat and bulky hybrid, I'm not in the same league.)
