I was going for a century last week, and got caught in a HUGE thunderstorm around mile 50. I rode 20 more miles before I could find shelter anywhere (I live and train in the countryside), but despite the thunder and lightening I enjoyed it. The downpour cooled me off, and I could really see natures beauty as I rode into the storm and I could see it from a distance. I ended up having to bail out and call someone to come get me because the storm just continued. But on Thursday I went out with a century on my mind again, and the beautiful weather allowed me to ride 104 miles.
