Overall, it was a great experience. I loved my training plan, and most of my gear. Nike shorts are awesome, I'm obsessed with anything Nike Dri-Fit.
I HIGHLY recommend calf compression sleeves for both running and recovery. I had some serious knots in my calf toward the end of training due to my "pawing"form. Those in turn pulled on my shin, and my left leg was miserable the week leading up to the race. The calf sleeves made everything total bearable and are now a staple of my running gear. I used CEP and loved them.
For energy/nutrition, I definitely recommend PowerBar Performance Blends before and Gels during. They are gluten-free, woot! And give you the energy you need. I had a Gel at about Mile 4.5 and Mile 9, and it was perfect. The Green Apple flavor is pretty darn good too.
My only disappointment was my shoes. I ran in New Balance Minimus Zeros. They are a minimal, zero drop shoe. The minimal part I love. The zero drop I love. The seam that they for some reason decided to place under my foot, right at the ball of my foot? I did not love. Over a shorter distance, it wasn't so bad. Once you crack 10 miles, it was miserable. Awful. Horrendous. I could barely walk to the car. And I could barely walk the rest of the day. I ended up walking on the outsides of my feet just to avoid the pain from that seam, which of course made the rest of my feet hurt! I wanted to love my Minimus. I did love them for about 13 of 16 weeks. But my first post-race goal will be to get new shoes and break them in so I can go find and run another Half.
Update: I contacted New Balance and received a very polite response telling me that it was most likely my shoes were defective. Despite the heavy use, they offered to replace my shoes. I ordered a new pair of Minimus Zero, and ran the Ann Arbor Half Marathon in them. The seam is still in the same spot, but has not caused any pain or problems. I am still currently running in Minimus Zeroes (as of July 31).
