I have recently started running again after a 6 year break. Previously I ran 5 miles several times a week, having started using the couch to 5k program. I completed that on my treadmill and then progressed to running outside.
This time I have no treadmill so i'm doing couch to 5k outside on the road from day one. While not having run for a long time i have walked my dogs most days 4 miles at a steady 4mph pace, so not starting from zero exercise.
I completed weeks 1 & 2 relatively comfortably and moved up to week 3 as of monday. Monday's run sucked, i felt really uncomfortable from the first 3 minute run. I decided it was just an off day and tried again today and I still can't make the 3 minutes of running. It's not my legs, it's my lungs failing me.
I know my pace is probably faster than it should be (for me, not in general), but despite getting prompts in my headphones to slow down i don't feel comfortable running slower.
So do I keep repeating the week 3 runs until they are comfortable, or drop back and repeat week 2, which i already felt comfortable doing?
