A.M. 10.1 with Jeff in 1:15:31. Did explosions. Discussed the importance of big O in computer algorithms. Ran two fat miles. First in 5:56, second in 5:50. Interesting feeling in the second mile. In the second quarter felt very smooth, and ran 86 uphill, but it did not feel that fast. In the third quarter I thought we were going to get 85 for the effort, but it was only 87. Possibly because of the turns. Then in the last quarter felt smooth again and ran 84.
2 more with Benjamin in 17:33.
P.M. Ran barefoot. 0.5 with Joseph in 5:45. 1.5 with Jenny and Julia in 14:59. They both were not feeling well, so we ran slower and cut Jenny's run short.
