I'd like to leave a memo about the last race for my future reference.
Probably because of icreased numbers of runners, it took longer time for me to go through the start jam. I find I went to have a rest at the same point as 2012 (15-16km). It took about 20 seconds for me. go I ran at 5-10 seconds slower pace compared with 2012, but the pace was constant in 2-35 km. My pace got slower when I went over a bridge, and it was also as 2012. I could spur after 40 km, and enjoyed the last spurt.
I found 'Mario' run in front of me when I reached the last leg of the course. Then I passed him. How hard it is to wear such thick overalls!
