We have rescheduled our trip to Arizona for a week in January that includes the Martin Luther King holiday. It turns out that the Phoenix Marathon is that weekend so, in an act of craziness, I signed up.
I suspect that I am going to find this experience different from my experience at the Twin Cities Marathon in October for several reasons. First, I can be certain it won't be humid. Second, the atmosphere is likely to be quite different given that, with 30,000 participants, the field for the Phoenix Marathon will be 3 times the size as the field for the Twin Cities Marathon, and there will be 26 rock n' roll bands stationed throughout the course. Third, the course is flat. (The evil part of the Twin Cities Marathon is that miles 20-23 are steeply uphill.)
At least I can be reasonably assured that I won't gain weight this holiday season.
UPDATE: I was wrong about the number of participants in the Phoenix Marathon. Turns out the 30,000 number that I had seen was for both the marathon and 1/2 marathon. See here. The field for the marathon is going to be only slightly larger than the 10,500 field for the Twin Cities Marathon.
