My first attempt was a DNF.
Well, I wouldn't even focus on the raw number. It was following my weekly mileage number. My max long run was less than 20% of my max weekly mileage. I didn't and still don't look at the 30 miles as all that long really, all things considered. Of course, I also don't put too much stock in the long run. It's just one of many parts of the overall plan.
