A bit late but I'll chime in on speeds, etc. The loop I do every weekend is 15 miles and takes exactly 1 hour. Going clockwise, it's all right turns and uphill the majority of the way and I average 15mph (obviously). There is one steep downhill where I hit 40.6mph a few weekends back which is kind of scary but quite a rush. I'm absolutely LOVING road biking... to the point where I have yet to take out the mountain bike but I do plan to change gears to MTB when the sand hits the streets in the winter. I second what someone said earlier about having a good road bike and a good mountain bike. Now is also an AWESOME time to buy a bike. Most 2011 models are 25-40% off.
