For some unknown reason, last Monday I started thinking abut training using some sort of heart rate system.  I started looking through books and websites and then someone on the Master's Group pointed me over here.  I read/skimmed (multiple times) most of the sticky threads, ordered a copy of the Maffatone Method, and started running at MAF (180-53=127).

Today I read the book and was inspired to keep going.  I have occasionally worn my heart rate monitor while running in the past and looking back over the runs I typically average 148-155bpm with a max around 165.  I don't think I have any aerobic engine at all. 

I haven't decided what to use as the MAF test yet.  I'll get around to it.  I'll stop by and see what people are doing here and update my progress.  I just started on Wednesday.  I am running 11:30 to 12:30 miles for the first couple and as the miles increase I am hitting 14:00.  Feels good so far though.  A nice change of pace from what I've been doing for the past 20 years.
