Running 1:05:00 [2] 10.3 km (6:19 / km)
ahr:168
Steady run from home aiming to keep my heart rate around 165. I was generally pretty good at this, although I recorded an average HR of 187 in the first km. I found it hard to maintain a steady heart rate, but I did deliberately pick a route which only had short sections of tarmac and quite a few hills. I tried to focus on using my arms and keep good form, but I'm not sure how successful that was.
