9 mile run, low heart rate, fast pace

I am trying to maintain the running mileage this week, so was determined to get 6 miles at least in tonight. Set out at 10pm and just felt really good, despite doing the 8miles yesterday morning. I was surprised to see the pace consistently below 9:00 minute miling, and still HR was hovering around 70%, and indeed stayed there for the whole run. It felt so good I did the 4 miles up to Letchworth, added another half a mile and then headed back for 9 miles at 8:47 pace and 70% WHR is way ahead of where I thought I was or planned to be – happy days!
