RNR Savannah training - week 1, day 2

The past few days we've had scattered thunderstorms in the area, so running outside has been chancy. So I went to the gym to run on the TM.  In an effort to try to up my miles, I planned to run the '5K loop' routine twice.  And instead of focusing on running for time, I focused on running for distance:
Walk (4.0 mph) - 0.25 mi
Run (4.5 mph) - 0.25 mi
I ran my loops back to back, breaking only long enough to write down my stats and reset the routine on the TM.

Round 1
Mile 1 - 14:10
Mile 2 - 28:41
Mile 2.52 - 35:34
371 cal, avg speed - 4.3mph, avg pace - 13:54

Round 2
Mile 1 - 14:09
Mile 2 - 28:18
Mile 2.53 - 35:11
370 cal, avg speed - 4.5 mph, avg pace - 13:57

C/D - 5:00
0.24 mi, 20 cal

TOTAL
5.29 mi, 1:15:45, 761 cal

Trying to run for distance was somewhat difficult -  particularly through the 'run' segment.  I really wanted to quit, each time, but I pushed through.   I Some of the difficulty was certainly in part to my breathing. My knees held up well - the new ASICS really helped.

Now for my shower and on to bed.

FOOTNOTE: I entered my stats into a couple of online training logs/websites, and noticed that the data from the TM was close:

JustFinish: avg speed - 4.19 mph, avg pace - 14:32
DailyMile: avg speed - avg pace - 14:19
