I am not connected on Garmin Connect with anyone who has run the Boston Marathon, but am going to run it this month. I am able to find it as a "course," but that does not as far as I can tell provide me with mile splits for whoever posted the course. I want to figure out some rough pacing for the various segments, and would like to see basically the same data I see whenever I upload an activity (esp. elevation gain), preferably for someone running about 3:05 to 3:10. Am I missing something really obvious? Any suggestions or links appreciated!
