There were a few stretches where we ran 12 - 14 minutes because of a nice downhill, and we walked Field's Hill (2 miles, rising 800 feet) and Botha's Hill (1 mile rising 400 feet), but we generally stayed with the 10 and 2 schedule through the first half of the race.
I timed each 5K of the race, as a way of checking how consistent we were--it's long enough not to be too influenced by an uphill or a downhill but short enough to provide sufficient data points. What I discovered was surprising, in a positive way. Here are the 5K times through the first 60 kilometers of the race:
5K 37:03 10K 35:43 15K 34:18
20K 32:33 25K 39:24 (includes Field's Hill --800 feet up in 2 miles)
30K 33:20 35K 35:06 (includes Botha's Hill--400 feet up in 1 mile)
40K 33:16 45K 33:45 50K 33:34
55K 31:20 60K 31:30
Halfway was at 43.5K. As you can see, we were getting stronger the further we ran. This is not because we are such he-men (sadly), but because the race strategy of staying out of oxygen debt and not letting our legs take a pounding on the downhills was paying dividends. By 60K, the temperature was getting above the comfortable range for me, and we were on a long stretch of the course with no shade, so I had to slow down. I am pleased to say that Cory did not. More proof of the soundness of our strategy.
Cory volunteered to stay with me as I slowed down, so I had to pull the old "I'm right behind you; just keep running" ruse, then hide behind other runners so that he had to go ahead on his own. (If you look at the race from the proper perspective, I really was right behind him, in that I was much closer to him than, say, the west coast of Australia) Even though I slowed down, I was running the 5K segments in 35 to 37 minutes. Cory, I can estimate, was running them in 30 - 31 minutes.
Then there was Polly Shortts--the last named hill. It was about a mile long and a rise of 300 feet, making it the least steep of the hills, but at nearly 50 miles into the race, it is a hill that everybody walks. Some runners run 50 or 100 yards of Polly as some sort of macho thing, but the reality is that Polly always wins. We met a guy who ran a time of 7 hours 5 minutes (a pace of 7:52 per mile) and I asked him, "Did you walk any of the race?" He looked at me like I was slow-witted and replied, "I walked Polly's, of course."
Even walking Polly's, my second half was only 15 minutes slower than my first half and Cory's second half was 12 minutes faster than his first half.
As Cory and I prepare for the Leadville 100, I am a believer in the strategy from Comrades. You don't help yourself by going out fast to "put time in the bank". As long as you are ahead of the cutoff times and running comfortably, you are where you want to be. As the race goes on, the cutoff times get longer, so simply by maintaining your pace you build your cushion.
I also want to voice my agreement with Cory about the Comrades experience. So many nice and helpful people. Such a great running atmosphere. Such a memorable course. A special experience that I recommend to anyone who can make the trip.
