I'm inspired but Laura Muir, and am wondering about racing strategies and why more runners don't just go for it. It seems to be common wisdom that when someone takes off at even pace they will likely get caught when the rest of the field is in sit and kick mode. Let's assume a 1600 m runner for example who drafts for 3 laps at 62 second pace, then kicks the last lap @ 54 sec for 4:00. Trackbot says that at even pacing (assuming no drafting) this is equivalent to 3:54.7. So, if that person could race themselves even paced vs. sit and kick (no drafting in either scenario) the even pacer would win by over 5 seconds. Is the drafting for 3 laps worth more than that? From what I've read drafting is easier by about ~1 second / lap at this pace. Is it worth more than this if it's really the case the the sit and kicker has a big advantage, or does psychology play into this? Maybe it's just too hard to get your best performance when you are all alone out in front? Why does sit and kick usually win?
