I used to run 400's but stopped about 3 years ago. At the time, my PB was 48.19, and now I don't have a coach as I'm doing this by myself. I'd like to get a beginners' workout to get myself back into this…does anyone know where I can find one.
I'm 6'0, 185 lbs, if that matters. I'd like to be able to run around 48 by the summer if possible.
