Funny this should appear here, as I just got off the treadmill and came to put it in the diary. The diary says that the last time I did it was 16 months ago! But I feel great and I will keep it up. 150 bpm for 40 mins every day. For me that's a little under 4 miles.

I will continue. I feel great. I would love to do it outside but I can't keep up the pace without a heart rate monitor calling the shots.
