you got a really tough year with the heat. Buddy of mine went out way too fast and ended up dropping at mile 77. He still averaged like 12 min miles, even with a death march toward the end before dropping (~19 min miles for the last 12 miles), so that gives you an idea of how quick he went out.
Give yourself a lot of credit for pushing through those conditions.
