Will this be enough to maintain basic running fitness?

I've been struggling with running lately and suddenly my endurance has taken a big hit. I think exercise induced asthma may be the culprit and I'm seeing my doctor this week. Until I figure out what's the cause I'm managing to do 2 mile runs and eventually I'll build up to what I was doing before (15 miles/week with the hopes of improving this). Will these 2 mile runs help maintain basic running fitness or should I try to up it or cross-train?Will this be enough to maintain basic running fitness?At least you should take off two weeks a year from running just to rest and recover. You can row, cycle,swim,walk,or cross country ski. Weight training with light weights and high reps is a good idea too.After two weeks, try a two mile run.If it feels good, go three times a week. Then start increasing your distance by 10% a week one day a week and then do your two mile runs twice a week. try to avoid treadmills.They do not work opposing muscles.

Cross training probably isn't a bad idea though, in addition to the running.Will this be enough to maintain basic running fitness?You are doing just great, people living with asthma should start slow and work their way into the workout and cool down is also very important. With extended worm up and cool down, you should do fine.
