Hey, stop-starts-stop-starts really no issue.
When i started to exercise with racewalking after COVID C B period, also short distances and stopping to drink water etc, it was just 2-3k distance, sometimes double sessions in the day 2 x 2k. Just get into the habit......but of coz that time it was easier coz WFH and really nothing else better to do on weekends.
It usually takes some 3-4 months to really solidfy your efforts into a routine, so much so that then it becomes automatic and much less resistance to get out of the door.
But best is still if it becomes a hobby. Unfortunately for running for me, it cannot become a hobby that pulls you out of the door. But cycling can, so that's why i can spend 10 times 20 times more time out there.
But if you really enjoy the marathon distance and long runs eventually, it's 3/4 of the battle won.
Strength + plyometric training simultaneously also can watch youtube, i use mini bands and the longer 2.08m bands (get from taobao for the whole set ) and you can do your split squats and deadliffts while watching.
In fact for running only, you might not even need to do deadlifts, just concentrate on any type of single leg split squat.
Same goes for mini band isolation exercises on hamstrings, psoas, glute medius and adductors groin muscles (adductors i just use my hands to resist lol, it's not very impt anyway but i just do coz it just takes 30 seconds all these exercises can be done consecutively as superset wo rest so why not).
Single calf raises you can also do in the bedroom with both hands on the door handle to give 20-30kg resistance and watch your youtube.
Additional exerises can include plyometrics......actually 2 simple plyo exercises only, drop jumps (vertical) and some sort of bounding type for horizontal plyo. Im only doing vertical plyo though
So far so good no injuries/niggles.......but if you train up really slowly and really are consistent with your work outs, no reason to get injured. Do not ego.
The same goes for other things....... recently i ego try a bit with one arm deadhang and overpushed, gg......1 single instance only. Tendonitis, 2+ months out of action.
my stop and start is.....i train up for a hike or event...then stopped.....completely......until the next hike
yeah getting those resistance bands, yoga mats and such. improve flexibility also. hips and hamstrings damn tight.

Lasts a good few years......no burnout effect.
