In a couple weeks, I'm running my 5th consecutive Boston Marathon and hope to pace a little more responsibly than I have in the past. I usually use a custom wrist pace band that is based on my marathon goal pace, adjusted for the elevation. In other words, my goal marathon pace minus or plus a few seconds for uphills and downhills. I use workouts on my F5 plus to help guide my training runs (tempos, fartleks, intervals and long runs) and am comfortable creating custom workouts. I was thinking of creating a "workout" with 27 separate steps to account for each mile in the race. I could create a pace target for each mile that corresponds with my planned split pace for that particular mile, with alerts to notify if I'm running too fast or too slow, much like my workouts now. Has anyone successfully created or implemented this in a race?
Maybe I'm just geeking out and need to set my watch to show current and last lap pace and use my good old wrist band...
