This weekend I ran the Air Force Marathon (Dayton, OH) as a training run in preparation for the Marine Corps Marathon in six weeks. This is the first time I've run a marathon as a "training run" (i.e., I didn't "race"). My previous long runs (3 20s) were done at 10:15-10:30 pace and usually with a very strong finish. I decided to start out at 10:30 pace and see what I warmed up to, although I didn't want to go faster than 10:00. The weather was perfect ... approx. 50 at the start ... 60 at finish. The course was mostly flat except for the hills noted below. Here are my splits and HR data:
Mile 1 ..... 10:28 ..... 139 ..... (HR read high first mile)
Mile 2 ..... 10:21 ..... 132 ..... (up hill)
Mile 3 ..... 09:33 ..... 126 ..... (downhill)
Mile 4 ..... 10:03 ..... 127
Mile 5 ..... 10:05 ..... 127
Mile 6 ..... 09:56 ..... 128
Mile 7 ..... 09:57 ..... 126
Mile 8 ..... 10:06 ..... 127
Mile 9 ..... 10:05 ..... 129
Mile 10 .... 10:02 ..... 127
Mile 11 .... 10:00 ..... 129
Mile 12 .... 10:17 ..... 131
Mile 13 .... 10:12 ..... 133
Mile 14 .... 09:59 ..... 132
Mile 15 .... 10:01 ..... 131
Mile 16 .... 10:01 ..... 131
Mile 17 .... 10:05 ..... 134
Mile 18 .... 10:09 ..... 136
Mile 19 .... 10:09 ..... 136
Mile 20 .... 10:25 ..... 138 ..... (Hill)
Mile 21 .... 10:04 ..... 136
Mile 22 .... 10:00 ..... 138
Mile 23 .... 10:10 ..... 142 ..... (small hill)
Mile 24 .... 09:37 ..... 144 ..... (hill)
Mile 25 .... 08:56 ..... 142 ..... (down hill)
Mile 26 .... 08:54 ..... 149
Mile 26.2 .. 07:49 pace .. 155
My Garmin time was 4:22 (9:57 pace), but I stopped the watch during a few potty breaks, so my official time was 4:24 (10:06 pace).
I was very happy with the race. I was particularly surprised (and pleased) with how my HR stayed relatively low (my MAF is 133). I ran a strong, consistent race and was able to finish very strong. It's a lot more fun passing people those last few miles than it is being passed. My recovery is going well ... I have a moderate amount of soreness in my quads, but nothing like after racing a marathon. I expect to return to LHR training today.
I don't know how this translates into a doable race pace, but my PR is 3:49 and I think I'll be able to beat that at Marine Corps. I had fun running a marathon this way and this would not have been possible without following a LHR approach.
Added: I would be grateful to get some feedback on:
1. As a training run, how was my pace/HR combo? Too fast ... too slow?
2. If I had intended to race that day instead of train, does the pace/HR data suggest what would have been a good race pace?
Thanks to all for the help.
