So here a I am mid way through my first week training for the marathon. Today was my third run and according to the schedule I am supposed to iterate running and walking at a 6:1 proportion. i.e run 3 minutes, walk 30 seconds, etc.
I finished feeling out of breath because I upped the speed quite high (for me) at the end. My average heart rate ended up being 154, which is 77% – 81% of max depending on what my max really. Either way, it is higher than it should be for today’s run. My average pace ended up being 11.11 min/mile
