It's a 5k. It hurt like hell...then I tried to pick it up. The end.
I split my runs up when they're split up on my watch -- it would be too much manual work to put them back together to enter them. Plus I'm already doing tedious manual work because this site doesn't handle feet in partial laps, and doesn't compute pace time for laps (and I want to see it for the partial laps) -- I want to minimize the amount of manual work I do, and maximize how much I can get the site to do.
Plus, Eric, the guy who runs the site, seems to often recommend entering a single workout as several pieces any time something about it changes, so I think his philosophy is that it is fine to enter a single run as multiple workouts. The summary graph combines them decently as far as I can tell.
When it’s all said and done, will you have said more than you’ve done?
Sure it does. You just can't see the interval/lap paces until you go back and view the workout - you can't see them in edit mode. For example, here's your last workout with intervals defined. Notice the paces for the full and partial laps. You are right that the site doesn't allow the input of feet - but is easy enough to convert in your head to yards.
Could you try slowing down your long runs?
