""...the truth that someday, you will go for your last run. But not today—today you got to run." - Matt Crownover (after Western States)
Apparently you don't need to run slow in order to make use of the "start early" option, though? Your link shows quite a few people running sub-3:00 with an "E". But perhaps people who are really gunning for a PR would try to do it with fewer runners around to get in the way? It still doesn't make sense, some how...
By the way... check out the 80 year old who ran a 3:20! Go Wally!
