Many folks who do Crossfit hate running...or have at least learned to hate running...and rightfully so. The reason they hate it is simple; they are simply running too hard. This is not their fault. It's been sold to them this way. Most just need to slow down.
Running is not for everyone. But if you feel it is something you would like to do...but just can't seem to grow to like it...the first thing to try is SLOWING DOWN. Run easy...take walk breaks. The safest and most sure-fire approach is to run at a heart rate that does not exceed a pulse rate of 180 minus your age. The best way to do this is use a heart monitor. Dr. Phil Maffetone came up with the 180-Formula method. You can read how to do it exactly right here.
Once you get used to feeling of training aerobically, you won't need to rely on a heart monitor so much. In the beginning, it's just a good biofeedback tool.
