Just using the garmin thus not posting here really much on the running. But ran 4 miles in 30:47 last week, even stopping twice to tie my shoes. PB of around 90 seconds. (although my time still drops way off for that distance.) Today ran a mile in 6:34 which is a pb by about 16 seconds. Both pb's from more than 6 months. A bit of fast running twice a week but otherwise 80+% nose breathing running. 30 to 35 miles a week. It's working.

I can see sub 6 minute miles as a possibility now. Will probably need to slog through hundreds of miles for it to happen though.
