I get the hybrid thing though, if you're training for marathons you have to dedicate a lot of time to running and you get pretty fatigued/need recovery which does not lend itself well to doing strength training.
Also running sub 3 for a woman is a very different feat to running sub 3 as a guy, her goals 3:11 etc. might seem odd but she's at the point where running faster means slight improvements i.e. 10-15 seconds/mile. Generally from you know training how much time you can reasonably run splits so you try to set reasonable goals you can be happy with. A goal of 3:11 was 4 min better than her prior time I believe, which would be about 10 seconds per mile faster.
