Threshold workout

Today was threshold day... i.e., keep my HR at 85% max, or about 162. I did an acceleration workout, from 140 to 160 over 20 min, and then kept it around 162ish for 30 min, then cooled down. I walked from our house to SugarHouse Park, around the park twice, then up to Browning Ave on 15th E, and then home. As usual, I don't particularly enjoy pushing this hard, but I had a great workout. I walked really fast (just under 10 min miles) and felt strong and fluid. I really feel like my technique is getting better every day :)! If only I had regular, good coaching... but at least I do feel like I'm improving without that. Practice makes perfect.
