Today's ride felt hard. It was supposed to be "event pace and terrain-specific". I averaged 13.37 mph, not too bad, but it's now obvious that my hoping to ride a century at 15 mph is overly optimistic.
As to "terrain-specific", that's impossible when I don't have hills anywhere close by. I did about five very hard efforts of one minute each, in a hard gear. That's about all I can do to simulate hills, except to make such intervals longer!
The ride was supposed to be four hours, but actual roll time turned out to be 3:37:20. I was getting very tired, and was running low on water besides. It's possible that I felt tired because I needed to drink more water, but my post-ride weight was more than my pre-ride weight. And I was using electrolyte drinks as well. Thus I don't think I was dehydrated. Maybe I needed to eat more?
On top of that, maybe I actually worked too hard yesterday. For a ride that was supposed to be "cruising", I spent a lot of time at lactate threshold. I tend to get hung up on speed, which isn't always a good thing.
I began today's ride by making seven circuits of the local park. The path was in a mess because of yesterday afternoon's downpour. Now my poor road bike is all mucked up :(
