Marathon countdown - 4 more days

Had another early morning run today. I covered about 14k (8.7 miles) in a time of 1:01:30h (4:24/km resp. 7:04/mile). Pace was a bit lower as I intend to start with on Sunday.
Weather is really fine for running, today in the morning we had around 12 degrees Celsius. I hope for same conditions on marathon race day ;-) The last two years we had to fight with bright sunshine and up to 30 degrees Celsius, obviously tooooooooooooo hot.
I am still struggeling with race tactics for Sunday. I'm worrying about being not fit enough to stay the course with a 4:16/km (6:50/mile) and finishing in less than 3 hours. Let's wait and see.
