S7H. T=50-55 degrees. Nice. Ran 16 miles with Joe and Karen H. at very relax easy pace. Hydrated well. Took 2 GUs and 3 Cliff's blocks. First 12 miles are on first half of the Marathon course. It has many rolling hills with equal or longer downhill portion after each hill; good for recovery. Most of the hills are fairly short and gentle incline. Not as bad as many people think. Felt like I could run at this pace for another 16 miles today! |
