Bike - 9 miles

Two loops of 4.5 miles. My first time ever riding with multiple bike riders. And, the roads were open to traffic but it wasn't too big of an issue. What was an issue though was that on the second loop, my bike decided not to shift gears while going up a big hill. I lost momentum and had to stop and walk up the hill, which sucked, and once again pissed me off that I have to rely on a piece of equipment that can have its own failures.
But, I didn't let it get me down. Here I am giving Michelle my "I am totally killing!" look.
Bike = 36:40 for an average speed of 15 mph.
