I would say start at 2 miles. Run that, if you still feel good, don't stop. It's important to build up your distance, but it's not something that takes forever to do. If you play soccer and you are use to running, it wouldn't surprise me if you could just go out and do 8 or more. The only thing you need to watch out for are hills. Especially if you are only use to running 1 mile and building up your distance. (Avoid hills until you can do a solid distance workout)
If you are trying to "like" cardio, you just need to go out and run. Eventually something may, or may not, click and you'll be hooked on running. (For me, this happened the first time I ran over 6-7 miles and just didn't want to stop. I ended up running until my body didn't want to move lol)
If your goal is to start doing more cardio, start doing 2 miles minimum. Then for now, maybe like every 3rd running day do like 4 or 5. When your comfortable with running for 30minutes or more straight everyday, you could build yourself a workout. That workout would look along the lines of:
Monday: Mid Distance (4-8mi). Tuesday: Distance(8+). Wed: Easy run(2-8 of relaxing). Thursday: Tuesdays workout +2mi or more. Friday: Easy Run/Mid Distance depending on how you feel. Saturday Easy run. Sunday Rest.
Hardest workouts would be Thursday. You warm up for the week monday after the rest day. Run and get your distance legs Tuesday. Relax wednesday and keep the blood flowing. Kick your ass thursday. Warm-down for the week friday. Relax Saturday. Rest sunday. If you want to add hills, add them where you feel comfortable. I'd recommend mid week so Wed-Friday.
To keep things interesting when/if you get in to longer runs: Vary your pace. Learn your distance markers (like 7th lamp post = 1 mile or whatever) and challenge your self by picking up your pace every mile or run like 1 mile faster then pace then pace the next mile. Or "back-half" your run. Run the second half first than the first. Works well on the shorter runs (4miles or under.) You could say, run your first 2 miles at 14min pace then the 2nd 2miles at 12min pace. This helps with endurance at the end of the day. (For example: if your in a grueling soccer game. In overtime. This kind of workout, the back-halfing, will get you use to being tired. So you'll have more energy than most people on the field when you need it. Although, since you're a keeper, this kind of endurance isn't really needed haha. If you ever wanted to switch to a forward you'd be set!)
I personally like doing descending interval stuff and back-halfing my runs.
