I've done a single 1 mile race, managed it in 5:46. Hoping to have another go sometime but there don't seem to be many 1 mile races around.
I reckon a 10% improvement over 6 months is probably realistic, so I reckon I could get pretty close to 5 minutes. If this hypothetical 6 months includes professional coaching, nutritional, physio, etc then under 5 minutes should be doable.
