Honestly, I'm happy going 15. The impetus for my question is entirely thinking about what it is going to take to get that century under my belt. Maybe I shouldn't even consider it for a few more years. My distance appreciated nicely over the course of the first 6 months of serious riding, but the speed did not. I didn't know if it would come with time or you had to train to achieve it.

I remember last June I was just starting to really get into riding. I had worked my way up to 20 milers and felt good about it. I went over to the Harpeth River Ride here in Nashville just to check it out and maybe get a glance at Lance and was watching the folks come in from the ride. I was amazed when a 'grandma', maybe 65, came over the finish line after riding the 62 miler. Unbelieveable! This year I'm going to ride that 62, so it's neat how your perspective changes.
