Saturday Ms. HH and I rode the East Bay path which goes from Providence, RI to Bristol, RI, 15 miles each way. On the way down I felt like I was having one of my best rides yet. My legs felt strong and everytime I glanced at my cyclocomputer I was doing between 17 and 19mph. So we get to the end and I check the Avg reading and it says 12.9mph, WTF.
So I got thinking, there are at least 10-12 intersections to cross in which of course you are slowing and then starting up again. That coupled with the occassional slowdown for other riders and the avg is blown to hell. So what's more real, the 17-19mph that I was doing when I actually had open space or the reading on the computer. I think it's all rather meaningless. Even if you measured always on the same course, conditions would change from ride to ride. I think I'm going to just ignore it from now on..
On another note. On the way back we came upon this chunky young girl probably 13-14 years old riding an xmart mountain bike that probably weighed 30 lbs. She was having some trouble shifting as I could hear the constant clunking of the rear cassette as she shifted. She was paying so much attention to her shifting woos that she was all over the path. We finally got around her and for whatever reason she decided to hammer and stay on my tail. I pushed my speed up to about 18-19mph for over a mile. When I looked back, damn she was still not that far behind. It took another mile or more to lose her.
Get that kid a road bike
