Okay race day, just okay

The weather was okay, it was nice and sunny, but pretty cold, really. We got off to late start, so I took 3 "one last pee’s." That’s where you say "okay, one last pee before the start," but w/ the start being pushed back, it makes that a hassle. I have never ridden the RR course sat St. Leon, but I knew it had a really big climb in it. As it turns out, that’s about all it has. It’s otherwise a flat course. It didn’t suit me too well. We did only 2 laps of the ~15 miles course, so I had to us lap 1 to learn the course. That climb was definitely huge. It is one of the bigger climbs I’ve ridden. It is just under a mile long, gains almost 400’. That’s a steady 11% gradient. Hard! I was in the front (first few) over it the first lap. I started it in the group and it was like riding the Hilly 100 hills; people everywhere and me having to weave through them to get to the front. I decided that next lap I would have to be at the front before the climb. At the top on the first lap I shifted into my big ring and took off solo. This lasted all of about 2-3 minutes due to the road following the climb being long and flat. I was chased down easily. But the pack was all split up due to the climb, so the group was smaller.
So lap two when we hit the creek basin that the climb climbs out of, I moved to the front. But I moved up too early, not remembering exactly where the climb was. So me and another dude ended up doing all the pulling through the flat basin, then I pulled one other guy up the climb the whole way. He stuck to my wheel like glue and we couldn’t get off the front once we reached the top. We reformed and rode to the line as a group. There was (at least) one Team Saturn of Dayton guy off the front, but I finished in the next group, probably just out of the top 10. Not a bad day. I spent a lot of time on the front, but could never get off the front.
My stomach was completely wrecked after I was done. This happens when I rode really hard. I felt like total crap the rest of the day. I made it home and laid down for several hours and whined. Then I went to bed, whined some more and fell asleep. I feel fine the a.m., but I need to figure out what tied my stomach on knots after really hard efforts. I think it’s lack of salt. I’m going to experiment w/ e-caps (salt tablets) and see what happens. I get plenty of sugar from Gatorade/GU, but very little salt.
I’ll spin out on the rollers in a few minutes and see what I can do the rest of the week. It’s supposed to snow a good (bad?) amount tonight, so outside rides may be hampered. I had a good building week last week; this one may be done inside.
