Wouldn't say I'm a "serious" runner but I go through periods where I'm into it and I did a half marathon once. If you want to strength train *after* the half (as in you won't be training specifically for another big distance) then you could just do any strength program out there and run a bit on the side. I don't think you can be srs about long distance running and strength training simultaneously, but you can do the one srsly and the other not so srsly.
