Did 21 minutes at an average heart rate of 158 on Tuesday. This is a personal milestone breaking 20 mins - its a long time since I’ve been able to do that

Quite pleased with this run. Decided to try and judge runs on heart rate and time, rather than speed or distance covered. Want to increase time I can run at 160. Milestones will be 25, 30, 35 and 40 mins. Ideally I’d like also to get my heart rate down to 155 for these runs. Currently I can walk faster than my 155 running pace! I am amazed just how bad my cardio was/is. Am struggling as usual with my legs, especially calves, but seem to be just about managing that side of things.

Good thing is that there is so much room for improvement :)
