Running 3:27:00 
Marathon #3 - Chicago. Initial goal was to beat my Boston Marathon time but the last couple of week's sickness made me change goal to 3:20.
Started of running 4:30 min/km and I felt very comfortable. Ran with official pacers but so did lots of others so it was a bit crowded at times in the beginning, especially around the aid stations. Felt so comfortable around 10-15K that I even considered picking up the pace a bit but decided not to, knowing that 4:30 pace will eventually become tough to keep. Reached halfway point at 1:34:30 and 25K at 1:52:38. The next 5K was the first real drop, 4:45 min/km and 23:49 but still ok I thought, 30K in 2:16. Things started to hurt the next 5K though and 26:50 was a big drop in pace but nothing close that was what to come. Last 7K was ugly. Had to stop a handful of times and walked for a few times, and those last 7K took me 43 min. 5:20 pace would have been enough to make 3:20 but legs were done. Rail trail running isn't enough if I really want to be able to run deep in to the 30's without hurting. 2h of road is fine, but after that...
Aside from the last half hour, a great weekend. Millions of people on the streets cheering on. 12000 volunteers and 45000 runners! Very impressed by all this. Everything ran very smoothly. Weather couldn't be better either. Cool and sunny. Already looking at potential marathon's for next year.
