Long ride. Eat more

I decided that with the century coming up weekend after next that I should do a long ride to see what it would be like.
I built a 72.5mi route, set my alarm for 6 am and warned Terri that I would be gone for a while.
I brought 2 bottles of infinite and a cliff bar. About 750 cal total. The ride time was 4:20 but I was dogging it. I didn't have enough cal or water.
I had planned to stop for more water about 1/2 way through but Terri called and asked me to hurry bc the kids were driving her crazy. So I powered through with just one bathroom stop.
I think I could have made better time with more support. In any event I would think that 6.5 hrs will be doable.
I also don't feel like I got any real training gains from that ride. Just a numb lazy feeling.
I am officially going back to Crossfit endurance style training.
Today I did cf strength and a wod in the garage. The heat is picking up and it is good to do the work in the heat.
Strength: 3 Rnds of 4 6 8 of shoulder press, push press, push jerk.
15min Amrap: 5 chest to bar pullups, 5 toes to bar, 10 pushups. 14rnds, 5 reps.
Icing my Achilles. Played tag with the girls today. It was the first running of any kind I have done in a while. It felt ok. Hope I can get back to running soon!
