You'll notice that between the 40+, 50+, Cat3, and Cat4 an average of 11 people did not finish with a time.
Cat 4 - This was probably the worst 60 miles I've ridden in three years. My diagnosis is that I was not fully hydrated, and looking back on it I also did not eat enough. Being an afternoon race and only eating breakfast is clearly not sufficient. Also my first go in Cat 4. Once we got to the killer-grade opening hills, I spent probably the next 40+ minutes in red. I was with a chase group catching up on the long climb, but about the time we did was the time they took off again. Kevin and I both lost the group by the top.
So I continued on in a dreadful path of over-exertion and by the time I go to the second lap I was ready to toss in the towel. Out of sheer pride of not accepting a DNF myself, I continued. Kevin caught up to me on the long climb as I had lost my few other companions from the downhill. We rode together for quite some time, and at this point I could barely sustain a heart rate beyond 150 w/o a feeling of nausea (attribute to dehydration). After the sag wagon caught up to us, we were lucky to have some water refilled.
At the corner of Bow St, we saw Patrick Collins (Bicycle Alley) sidelined and we stopped for him. Apparently he had over-exerted and fainted. As he was feeling better at this point, he decided to refill as well and continue on with us. By the time we got to the long downhill, Kevin had departed from us, but I was feeling better after adequate hydration. So, Patrick and I decided to chase him down. He had a sizable gap that we managed to catch right at the line, hence all three of us have the same time, sorry Kev!

lessons learned - going in the red for so long is not a good race tactic. afternoon races require more fuel and hydration pre-race. I need more power in the 4's.
