I read an article in the Wall St. Journal a couple of months ago about the latest thinking about marathons - which is that there's no real harm in doing them pretty frequently.
So, I've been trying it, sort of. I ran a marathon in October, and a ran a 50k (31 miles) in November and another today.
I got passed by a nice 74 year old woman who was considerably faster than me. I had a nice conversation with her before telling her to take off without me.
We've had warm weather here. A lot. It got up to the mid-40s today, for example. I'm not sure I want to be doing these long runs outside in actual freezing weather.
When it freezes and there's ice
the footing's not too nice.
