Running or Swimming?

Today I felt like swimming. Or was it running. Anywho the weather has been terrible up here in the "icebox". Today I had to break things up a bit. I was looking for a longer easy day. 16 miles very easy as I am still recovering from the workout yesterday. I did an easy 9 in the am. I checked the weather.com current conditions prior to leaving for my pm run. Heat index 95. I considered carrying a water bottle but changed my mind last minute. The run went ok. 16 for the day not bad. I still have a little soreness in my calves from the workout on the mill yesterday.
