did my first ever 2 runs this week! advice?

did my first ever 2 runs this week, one on wednesday (the 16 min one) and one today (the 15 min one)

for context, ive never been a runner 😅 i usually walk but im super excited to start running more (and hopefully get those pace times down lol)

looking for gen advice on how to improve! also i ran both miles in intervals with 1 min running and 1 min walking+was wondering if that is productive or if i should change it up? thanks!!
