Sunday
10:00am - 10K race in Komazawa Park. This is a small fun-run type race held to promote the LA Marathon. Flat course, 4 times around a loop, near ideal conditions at 10C/50F (warmer in the sun) and no wind. Course seems accurate.
Total field of only 227 men, with several good runners (winner 31:52!), 6th 35:xx. There were about 12 ahead of me, and I always had some guys to run with or chase.
Felt good the whole way and ran well, with a 38:27. No km marks, but the loop is marked, so you can time 1km splits. The first one I timed was 3:48, others were low 3:50s, and I picked up the last 1k quite a bit. So 38:27 seems right.
