It's the Heat

Several runs of recent start at ~6:45/mile for 3.5M and then fade to finish at 8:30 leaving me exhausted. Runners World recently wrote one should add 20-30 seconds/mile for every 5 degrees above 60 degrees.

It's 12 days until I race to beat my old marathon course record Around the Lake. Will the heat be a factor? What can be done about it?
