I received my Garmin GPS Edge 305 last week and attached the cadence and speedometers which seem to work, I still have not figured out the actual gps functionality, I need to sit down with the manual, or bring the manual along on my next ride.
My plan is to get to 10 hours a week of riding and stick with that as consistantly as possible going into December. Last week I managed 7 hours -- Sunday greenbelt ride, Tuesday greenbelt ride, Friday Mt. Bonnel ride, and Saturday ATC ride. I detoured a bit on my ATC ride and did 44 miles total. It was great to actually see how far I had gone.
