Well, I should have expected this. Not a good day today. I've had way too many good days/rides thus far this season. Felt great mentally and I thought physically too, but my legs were just flat. There were a few guys from another club that met up with us today. They're faster riders, so the pace was quicker. By about mile 20 I was ready to turn around and go home. I was fine and fast, then struggling to keep 16 mph pace. Then fast again. I'm not sure what was going on, but I couldn't find the right gear, got stuck at the back of the pack where (what I call) the "slinky effect" is at it's worst. Fast, then slow. Fast, then brakes. Shift up, shift down. Draft, then get lost by the pack. All day was like this. Couldn't wait to get back to the truck and head home. Oh well, this day was coming, glad it's over now and hopefully will not happen again for awhile.
