Dashing through the snow - with "new toys"

Today was the coldest weather I've ever run in.  It may have gotten up to 23 degrees. And yes, there were snow flurries.

A few days ago, I received the hi-viz vest I had ordered from Dick Pond Athletics.  I have tried running with a belt with pockets to carry my phone, etc.  However, I don't like the way stuff bounces around.  I have "re purposed" a couple of photo vests by cutting out the back, but black and olive aren't very visible at night.  The Fuel Belt vest fits the bill-pockets and visibility.

The other "new toy" is the android version of RunKeeper.  This is the second time I used it.  Previously, I had tucked the phone in my pocket only to hear my phone tell me my time, distance and pace.  
Oh, I had to wear the ear buds.  
Because I run on sidewalks, I have to be mindful of any cross traffic, and haven't wanted the distraction of music or any other sounds from ear buds.  Today I wore the 'buds while the RunKeeper app was on.  I decided to cross check the results with my stopwatch, and the MapMyRun  map charting tool.
My route took me from my home  to the trail in River Park The trail follows the North Branch of the Chicago River. (btw. the water level in that branch looks really low!) Along with  one trip up & down the trail, I did a mile around the track close to Argyle St.
. I intended it to be a long slow distance run.  How one does an "lsd" run in such cold weather, I don't know.  I'm not sure I did.  I'd consider 12 minute miles "lsd".  
I'm going with the figures gleaned from my stopwatch, and MapMyRun.  I'm claiming 13.52 miles in in 2:29:00 with an 11:01 a mile pace.
Mind you, I stopped my stopwatch before stopping the RunKeeper app.  Yes, there was some fumbling around with the phone. However, I find the RunKeeper app results..um... optimistic. 14.01 miles in 2:30:25.  OK, I'll buy that.10:44 pace?  Meh, I'll believe 11:00.
On the other hand, the route that RunKeeper charted out was fairly accurate. 
On the way home, I wanted to break up the monotony of a long, straight run down Foster Ave., so I took digressions through the newly renovated Eugene Field Park, plus some side streets.
RunKeeper did get those digressions.
I still want to test out RunKeeper on a path with mile markers. I have Monday off, so I might try it again on the Lakefront trail.
