I started morning running 1,5 months ago and I decided not to start slow (with the time when to go up), but to make a hard cut. Instead of going up at 8 or 9 am, I went up at 6 without transition phase, because that helped me sticking to this plan. I think when you’re starting slowly getting up earlier each day, it’s easier to go back to old habits. Nevertheless I agree with the pace / distance slow start. Don’t run 10 km every morning at a pace of 4:00 min / km if you have never done this before 😂.
