Yes up to 4 miles now. I actually do about 7 but need a 5-10 break inbetween and i have a dodgy back and it hurts a bit too much.
Its only taken a few months of not really that dedicated work to get up to 4. At the moment i am doing 3x4 mile runs, 1x7 mile run on the weekend and 3x2 mile runs to fill in the week. I must say my general stamina has improved and i find sparring much easier.
welcome back. you are up to 4 miles now??? how long has it been since you started running? it's been about 2 weeks for me, and i'm still taking my sweet time to do 2 miles.
