Looks like my marathon training kinda worked

So my marathon training is all based on doing my longest run one month away from marathon day.  Leading up to that super long run and following that long run, I'll add/subtract 20 minutes from my run length every weekend.  So I'll do a 100 minute, 120 minute, 140 minute, 160 minute, 180 minute, 160 minute, 140 minute ... you get the idea.  It's like a bell curve of run lengths.

Here's how it mapped out.  Not too shabby.
