There are plenty. But, he wanted to run his marathon on the same day. So, we may go up to Lake Geneva in Wisconsin in May. But, I told him I don't want to run in the cold. This is how I have so much time. I am crafty.
Actually, you do. Temps in the 40's, at most into the 50's, are good running temps. Of course, that's an Arizona definition of "cold", but you get the drift. You really don't want to be running in 70-80-90's.
I ran a marathon a week and a half ago, and it was at or just under freezing at the start. 2-3 miles into it, a local business had a time/temperature sign out front that said 32degrees. Six miles later, there was another sign and it still said 32. Normally, I'd be freezing my butt off (well actually, no I wouldn't -- I'd be warm and cozy at home with the heater on
) in temps like these, but I was comfortable in sweats. I was actually getting a bit warm towards the end once the sun was high overhead.
But, whatever, good luck to you in this endeavor. You shouldn't have a problem with it.
