Wow you did a 50K in about what I could probably finish a 50K in (did 42K in 4:13) but I did a hell of a lot more training then you. Well done! You are also very fit. I am skinny fat. I am 5'11" 165 lbs 20% bfat according to my scale which i'm not sure is accurate. how tall are you? what do you recommend for someone that doesn't do any strength training? maybe start small with pushups or something? What's next on the horizon for ya?
