I would try Philly in the late fall. Pretty fast and a cool temps. The great benefit here is that if you qual, you can run in two Bostons because you would qual after the year's close out. So say you qual in Nov 2010 in Philly you can run Boston in 2011 and 2012.
I qual'ed in Philly in 2004 as a Clydesdale in the 35-40 group (3:12:07).
Thanks for the heads up.....I actually got a call from the Birth Mother of our 13 year old from Philly last week....we had been discussing possible trip back to meet her after adopting him 13 years ago...since my son has 3 siblings from the mother he has never met.....sounds like a good enough reason to plan a trip. I appreciate your input....
Keep up the good work and make Team Clydesdale proud
You might also consider the California International Marathon in Sacramento. It's in December, very cool, and a net downhill. I ran a 3:07:20 and was third Clydesdale finisher. Qualified for Boston by 13 minutes. Only problem, Boston was already sold out for this year.
