Wind
So I did my 10 mi a day early this week because I *might* attend a kickboxing class tomorrow night. Today's ride was interesting. I still did my Olympic route, but this time there was a West-East wind. So instead of hitting about 20 mph going west, I was doing about 16 mph. However, the benefit was that I was doing about 16 mph going east (instead of about 12 mph). I think I like the wind. At least it keeps my pace consistent.
