23 Minute Intervals

I've set the goal for 7.5 miles in 90 minutes.  It will be slow progress at first, but I have all year to really focus on not grabbing the bars or quitting.  I will push through.  Today was just walking for 90 minutes.  It's been about a month since I did any running.  So I started with the setting at the lowest setting and increased my speed by one click each time another 23 minutes passed.  I increased the speed by four.  Only walking, but I think this will catch up with me quickly.
