I have run this event a few times. Last year I ran it just 3 weeks after my 100 miler. This year, it was 4 weeks. My body felt much better than last year.
My intention was to relax and enjoy the beautiful fall scenery. Basically, an easy long run. In fact, I considered pacing the 1:55 race time, but was afraid I wouldn't be able to keep that pace. However, my initial miles were all around the 8:00/mile pace, and it felt easy. So I just went with it.
It never really felt hard, and I kept that pace to the end. The last 2 miles, I ran both at 6:57. So, essentially, I ran a 13 mile Tempo Workout. If nothing else, my confidence of being able to run a 3:30 marathon in January was boosted. The 18 weeks of training should make that possible, although today's race temperature of 2C/35F is likely a tad more favorable than Fort Lauderdale's temperature will be.
The 1:45 pace bunny came in at the same time as me.
